RE: Class C rear end sag and banging!

Note that the rear leaf springs on (some? all?) E series chassis of that vintage are rather flat by design, and appear on casual inspection to go straight on a slight diagonal rather than having much or any obvious smile shape. I'm not suggesting you don't have some spring issues to look into--it certainly does sound like you very well might; but going merely on the spring shape can be misleading on these vehicles if you're not familiar with the design. If the shocks are worn, it would be a good idea to replace them as well. A weak or worn shock is going to allow the suspension to bottom out more easily on a sudden transient than a new one (among other things). The rear shocks are not hard to replace on the Ford E series unless the motorhome builder has done something silly to limit access.

RE: private land camping questions, cell booster suggestions

The legality depends on locally applicable zoning laws, sanitation/environmental laws, and probably a few other laws. The answer would likely vary from place to place (and sometimes also depend on how many sites are involved), and possibly on whether this is done commercially for income or not, etc. In Vermont, the environmental agency requirements (sanitation and potable water and such) recognize four or more sites as a "campground" with specific requirements, while three or fewer are just camp sites and have much less regulation. That is in addition to any applicable town zoning regulations.

RE: Sailun Tire inflation tables

Look up the tire inflation chart for any manufactuer of the same type, size, and ply rating of tire. The pressures and weights are the identical, or close enough to identical to not matter for practical purposes. (If they were not consistent across tire manufacturers, the vehicle makers would not be able to give their recommended tire pressures on the sticker without specifying a specific tire make and model.) Here's the relevant data from Michelin; note that these weights are axle weights, and so must be divided by two or by four for a single tire's weight rating at the pressure:  75 psi: 6780 lbs single, 12840 lbs dual  80 psi: 7140 lbs single, 13520 lbs dual  85 psi: 7500 lbs single, 14200 lbs dual  90 psi: 7850 lbs single, 14860 lbs dual  95 psi: 8200 lbs single, 15520 lbs dual 100 psi: 8540 lbs single, 16160 lbs dual 105 psi: 8880 lbs single, 16800 lbs dual 110 psi: 9220 lbs single, 17440 lbs dual 115 psi: 9550 lbs single, 18080 lbs dual 120 psi: 9880 lbs single, 18700 lbs dual Of course, you should never exceed the maximum pressure rating for your wheels, nor the maximum pressure stamped on the sidewall of the tire.

RE: Campground Breakers - EDITED Impedance is the reason current draw goes up as voltage goes down. Impedance is the AC equivalent to DC resistance. A constant impedance would mean that the current goes down as the voltage goes down, rather than up. (And that of course is also true in the DC case with a constant resistance.)

RE: Campground Breakers - EDITED

I am not an electrical engineer, but I am a computer engineer (Master's from RIT) and that involved about 1/3 EE, 1/3 Computer Science, and 1/3 its own classes. Certainly there are many who know more than I do, but I'm not wholly ignorant of what I am saying...or at least attempting to say. It's very possible that what I think, and am attempting to write, is not quite making it into words very clearly. Power is defined as voltage times current (at any given instant, or an average integrated over time); I have no argument there, and of course the definition of power is not Ohm's law. Ohm's law relates voltage applied to something to current that flows through it, making the voltage proportional to the current with the resistance being the constant of proportionality. Many materials behave in this way in practical circuits, and so may be modeled as a resistor and analyzed using Ohm's law. This implies that the V/I curve for whatever being described is precisely linear, and passes through the origin. If the current through some device goes up when voltage goes down, then rather clearly Ohm's law does not apply to it, or at the least the resistance (or equivalent resistance) is not constant but is itself varying with the applied voltage in some fashion. For electric motors, the relationship of voltage and current also varies with the mechanical load applied to the motor, the speed the motor is turning at, and maybe some other things. A Thevenin equivalent circuit is a very handy analysis tool for linear circuits. It doesn't apply to circuits with components that have nonlinear behaviors, such as semiconductors, although often an adequate model may be derived by assuming linear response over some limited operating range. A silicon diode, for example, is hardly linear in its response, but can be modeled reasonably accurately by a pair of Thevenin equivalent circuits: a quite large impedance when reverse biased (the applied voltage is less than the threshold voltage of about 0.7V), and a small impedance with a voltage source equal to the threshold voltage when it's forward biased.

RE: austerlitz ny to promise land pa

That's probably what I'd to, too; NY 22 to NY 23 to I-87 to I-84. Possibly I migh take US209 rather than (much of) I-87, which is a little less distance and less toll but more time. Hopefully it goes without saying, but the Taconic State Parkway (NY 199) prohibits travel by RVs and thus I presume must be avoided. If by chance you're in a passenger car that would be a nice route to take.

RE: Stove fan

Other than just looking for screws and using common sense, is there a right way or a wrong way to disassemble the hood and fan? If you break something or otherwise can't get it back together afterwards, you probably tried to disassemble it using the wrong way. Likewise, if you spend three hours getting it apart only to discover that doing things in the opposite order would have taken ten minutes, that's the wrong way. ;) If it's anything like my RV range hood, it's nothing fancy or complicated. (Also if it's like mine, the fan is more decorative and noisy than functional, which for me is doubly the case as it's not vented to the outside but just recirculates the air underneath the hood.)

RE: Keeping cool

If you have a proper thermostat for the air conditioner, just set it to the temperature you want; it won't cool down faster with a lower thermostat temperature setting. What I generally do when driving is use the vehicle air conditioner and have a rear ceiling vent open (one with a vent cover over it) to help pull the cool air through the vehicle. The truck air conditioner is theoretically a good bit more powerful than a roof air conditioner, though it's somewhat limited by what sort of airflow you can get through the coils (and not helped by having the ductwork directly above a big hot engine). I think it's somewhere in the vicinity of 25,000 to 30,000 BTUs. Upon arriving at a camp site, if the interior of the RV is hotter than the outside air, opening the vents and windows will cool it down rather more quickly than an air conditioner can. I'm not sure running the air conditioner during that time has much bearing on things; the basic goal is just plain old air exchange. Maybe runnign the air conditioner's fan would help in some cases.

RE: thoughts on our 2019 Rubicon

What's your plan B if the mechanical key breaks? Or if the chip in the mechanical key breaks? A key fob is no different technology than a chipped key; it just doesn't have the mechanical pins and tumblers or equivalent mechanical doodads to get crudded up, break down, wear out, etc. Instead, you have a much more mechanically robust (or at least potentially more mechanically robust) pushbutton. The chances of it breaking down are lower than a mechanical key. On most if not all systems, if the battery in the key fob dies, you can still use it to start the vehicle through passively powered RFID technology; it just needs to be placed in a specific spot in the vehicle for the communication to work (rather than being anywhere in your pocket or whatever). If the vehicle battery dies, of course, you aren't starting your engine without help no matter what the key setup looks like.

RE: Cracked Water Filter - Freeze?

The hose itself is generally okay with freezing; it's stretchy enough to not burst. Fittings and such are a different story. Glad you noticed the hole before hooking stuff up and turning on the water!

RE: Selling Canadian MHome in US with no title

Did you not receive the Texas title when you purchased it? I'd think you ought to be able to sign that over to the new owner. (I'm not a DMV employee, though, neither for Arizona nor for any other state.)

RE: Campground Breakers - EDITED

(Incidentally, the suggestion that current always goes up when voltage goes down is absolutely incorrect for many loads. Electric motors and motor-driven equipment is a rather complicated case; the current may go up, down, or stay the same, at least within some reasonable range of voltages. If the voltage drops low enough, the current will of necessity go down; otherwise you'd have the air conditioner etc. consuming inifinte current when unplugged with the generator off! For resistance heaters and incandescent lights, the current (and hence power consumed) drops as voltage drops.) In other words, Ohm's Law is not a fact. WOW! I did not know that. Thanks for posting this new relevation! Ohm's law is a description of how many, but certainly not all, things behave electrically. Ideal resistors follow Ohm's law; practical physical resistors (including such things as wires and fuses) come very close indeed to the ideal, over a wide range of voltages and currents. Of course, for things that follow Ohm's law, the current is proportional to the applied voltage, and so goes down as the voltage drops. Things like semiconductors and motors under load and incandescent lights are not ohmic, some very much so, and for them the relation of current to voltage is different and generally more complicated. Ohm's law can still be used in some circumstances as a handy analysis tool, perhaps only under fairly closely defined circumstances. In other words, it's still useful at times to treat such non-ohmic things as their equivalent resistances at some specified operating conditions.

RE: Campground Breakers - EDITED

Assuming there was nothing else of significance consuming power in the RV, there is no realistic way two air conditioners should trip a 50A breaker on their own. If their current consumption is abnormally high, the 20A breaker for the air conditioner circuit(s) would trip long before a properly functioning 50A breaker. That ought to be true even if both air conditioners are on the same leg, which is not the way things ought to be wired up. If a bunch of other stuff is running at the same time, say an electric water heater element and the converter charging rather low batteries and the fridge and maybe the microwave oven, then one may be able to legitimately exceed 50A and cause a healthy breaker to trip as it ought. (Incidentally, the suggestion that current always goes up when voltage goes down is absolutely incorrect for many loads. Electric motors and motor-driven equipment is a rather complicated case; the current may go up, down, or stay the same, at least within some reasonable range of voltages. If the voltage drops low enough, the current will of necessity go down; otherwise you'd have the air conditioner etc. consuming inifinte current when unplugged with the generator off!

RE: Campground Breakers - EDITED

What was the current draw on each of the two legs with both air conditioners running? Without knowing that, it's impossible to say with any real certainty if the breaker was working properly or not. Standard breakers operate thermally (for the most part--for very high current overloads, such as a dead short, they have a magnetic trip mechanism that acts more quickly). The average current being consumed is measured by how much it heats up a little bimetalic strip, and if it heats up and bends enough it causes the breaker to trip. Anything that makes it heat up more will cause the breaker to trip earlier--higher temperatures in the box than expected, poor contact between the breaker and the bus bars it's mounted on, or I presume poor contact internally in its contacts due to repeated tripping/disconnecting under load. My guess is that the breaker is in need of replacement, but without actual measurements of stuff it's nothing more than a guess.

RE: TV recommendations for outdoor TV entertainment center

LED TVs are LCD TVs with LEDs for the backlight rather than CCFL tubes (cold cathode flourescent tubes). I would not generally expect one or the other to be more prone to trouble due to heat and humidity; the electronics are mostly similar. How exactly is the picture messed up? It may be a poor signal cable going to that TV, or a poor connection to it. It could, of course, also be a fault with the TV.

RE: Resort Campgrounds 2-3 hrs outside NYC?

Depending on the age of the kids, kneobels has two campgrounds one on site with the amusement park and the other has a shuttle. Not really resort type but 12 and under will really enjoy the park. A good suggestion. I was imagining it was farther from NYC than it is, else I would have mentioned it. 13 and over will really enjoy the park, as well, in my humble opinion. I know for sure this over 13 year old does very much.

RE: Resort Campgrounds 2-3 hrs outside NYC?

One possibility that comes to my mind is the HersheyPark Camping Resort, which is just a hair over 150 miles from NYC (per Google Maps routing). There's only a little more than the pool at the campground, but of course HersheyPark offers much much more to keep people busy and there's a shuttle service between them. It is a nicely maintained and well-run campground.

RE: Clingmans Dome and Cades Cove Smoky Mountains

I drove my 32' long class C aroudn the Cades Cove loop. I made it, so it's possible, but I would not do that again or recommend it to you. There are many relatively low branches over the road, and many people pulling "off" the road here and there and leaving precious little room to get around them. The length wasn't too much the problem, but width and height and general maneuverability are challenges. Parking at the visitor's center at the far end of the loop is entirely suitable for larger vehicles. Cades Cove itself was well worth seeing.

RE: Electrical help!!

Circuit board on refrigerator is toast. Heating element will be fine. Converter is toast. Microwave is probably toast. Some converters wouldn't be toast; PD at least claims that theirs can withstand 240V without damage (but won't operate at that input voltage). That said, most factories don't put superior converters in their RVs, so it's a good bet that it's toast or at least needs some work.
