RE: Generator handling?

If you are NOT running an A/C then a 2000W generator is plenty. Even it you are running an A/C a pair of 2000W generators are much lighter (individually) and easier to move and store. The problem is, I have not seen a duel fuel 2000W-2500W inverter generator which can run in parallel. Several after market kit to convert, but now the costs are getting very high. Many people have reported that you can start and run even a 15,000 BTU A/C (with a soft start kit) on a Westinghouse iGen2500, but that is gasoline only.

RE: exchanging propane cylinder that came with TT

Don't rule out operator error yet. I would go to a commercial propane dealer and see if the fill works. Great advice! Don't rely on your local service station clerk to fill your tank and assume they have been trained!! Times 3 !

RE: exchanging propane cylinder that came with TT

Are any of the exchanges still a proprietary fill that needs a special key? I have never seen a propane tank that required a "special key" to refill.

RE: Charging trailer battery while towing and smart charging

I run a 2 gauge dedicated run between my truck and trailer and use Anderson connectors for the link at the receiver. How about some "real world" feed back ! Next time you are hitched up, check the battery voltage at the truck battery and then the battery voltage at the trailer battery. For best results for this test, the trailer battery should be at least 10% discharged.

RE: Charging trailer battery while towing and smart charging

Start by running a heavy dedicated charge line between the truck and trailer. It will help in trickle and maintenance charging. If you want more, later you can add a DC to DC charger off this new run line. The wire that is currently there (probably about 12 AWG) is adequate. It is not worth the cost and labor to try and install a heavier wire.

RE: Charging trailer battery while towing and smart charging

The point of the DC-DC converter (charger) is such that you can ignore the voltage gyrations of the alternator and any voltage drop in the wire and get proper charging voltage on the trailer battery. You no longer care what the vehicle is doing or how it works. DING DING DING ! We have a winner ! Add in, most DC-DC battery chargers also do a "proper" 3 stage charge on the house battery. Or put another way, even though the trailer battery is needing a strong charge, the alternator is only putting out enough to float charge? Basically, yes. The house battery would charge but at that rate it might take more than 24 hours.

RE: More Genny wars

You can get the 3200w Firman inverter generator at Costco, for $100 cheaper. That weights too much for me to easily load in the back of a pickup truck. "What the RV world needs ..." is a 2800/2400 inverter generator that weighs about 50 lbs and has a run time of at least 8 hours at half load. The closest one to that is the Westinghouse iGen 2500

RE: 2 12v batteries---Mallard TT help

1) Getting a charge to the house battery from the tow vehicle while traveling. I use a 99 Suburban. ... Or hardwire it from the pigtail connection at the trailer and Suburban. I have run a charge wire from the front of my 1996 Suburban to the rear. The wire was already there from the factory, I just had to hook it up. And I have checked many times and it does recharge the batteries from 50% charge to full in the two hours it takes me to drive home from the desert. OpenSpaces write up is pretty good regarding charging from a 12V power on a 7 pin connector, but you may or may not run into a problem. Some time around 2000-2005 ALL cras and light trucks start using "smart charging systems". Various manufacturers do it differently and even the same manufacturer have made changes since they first started. These smart charging system put out the MINIMUM voltage to keep the starting battery charged, typically between 13.2V and 13.8V (about 2-5 minutes after the engine has started). This is NOT ENOUGH VOLTAGE TO CHARGE A HOUSE LEAD ACID BATTERY BANK ! Installing heavier wire will NOT improve this !! What you need is a DC-DC battery charger. Renogy, Redarc and Ctek all make them. They actually boost the available voltage on 12V power pin in order to properly charge the house batteries. 2) Issue two that I need to solve is installing two 12v batteries rather than one at the outside front of the Mallard. I am thinking, if I got this right, that I can put two 12v batteries behind the propane tanks. You would be much better off with TWO 6V golf cart batteries. They will give you more power, last longer and probably cost less. NOCO does make a plastic battery box that will hold two 6V golf cart batteries, but it needs support rail underneath where it is mounted.

RE: Will solid state batteries change the world?

Ford just introduced their new all electric Mustang with up to 459 HP, depending on model. And a range up to 300 miles on current battery technology. Obviously these manufacturers feel a battery breakthrough is imminent. You are putting WAY TOO MUCH into this EV announcement. What it means is that Ford believes there is sufficient demand (people with $$$)and the CURRENT technology is adequate to mass produce an EV. No big company "bets their business" on "an invention will happen soon" ! BTW, within the past 2 years Ford launched a new full size SUV (Expedition), a new truck (Ranger) and a new mid-sized SUV (Explorer). They will launch a new rugged SUV next year (Bronco). Only the Explorer is available as a Hybrid. Ford still is heavily "hedging their bets" on EV with a lot of old fashioned gasoline vehicles.

RE: Super duper plug in code scanner w. WiFi?

The "pro" level scanner do come with bluetooth dongles, but all of them seem to use a tablet size display unit, some smaller, some larger. The pro ones require a subscription service for constant updates. This cost at least $100/mo.

RE: first report new springs with a surprize result

My E150 started sagging at about 5-7 years, especially when I hooked up my pop up to it (NO WDH). Added a leaf, What a difference ! It does sit a bit high when empty, but I would rather have that.

RE: Battery Monitors

A "shunt" is a device that is used to measure how much electricity flows through it, so it can measure the amount of electricity flowing "into" a battery bank or "out of" a battery bank. It is typically mounted very near the battery. Some are connected on the positive side of the battery and some on the negative, it depends on the meter. Any decent meter will ship WITH a shunt and instructions on where to install it. The Victron BMV-700 is nice.

RE: Rated engine power

In the US, all light duty vehicles are rated using the same testing procedures defined by the Society of Automotive Engineers. It is horsepower at the rear wheels with all accessories installed (A/C is likely turned off). When you get to medium duty vehicles, I believe the horsepower is measured "at the crankshaft", but again with all accessories (probably not A/C). The important thing is that it is done CONSISTENTLY across all manufacturers.

RE: Alternator

If your chassis battery is fully charged, expect the alternator output to be a fraction of it's maximum rated capacity until the existing loads drop the charge in the chassis battery. Partially correct. The actual current (amps) output will be what ever is required to MAINTAIN the desired charging voltage. The point is, within a few minutes of starting the computer adjusts that voltage down to between 13.2V and 13.8V Ford engineers designed their charging system that way to improve fuel mileage ... Not just Ford. Every light and most medium duty vehicles. It has been that way for over 15 years. ... and to prevent people from doing what they want to do . . . . . charge the batteries in their camper with the chassis alternator. Yes I intended to run a heavy cable to rear for charging FW, I know that the is a orange wire with 40A fuse from factory ... You can still charge your house batteries, but it will require a DC-DC battery charger like from CTEK or Renology. And you won't need to use huge oversized wire to eliminate voltage drop !

RE: Is a fuse a fuse?

IIRC, automotive fuses rating are based on a maximum of 32VDC-36VDC. Voltages above that may cause the fuse to blow (48VDC) the fuse to blow "early". ktrmrfs is spot on with his statements. What people need to understand that the "variability" of a fuse. A 15A fuse will "carry" 16A of current for hours and not blow. It might even carry 20A for several seconds. Back to the OP original concern. ATO/ATC sized inline fuses older with either 10AWG or 12AWG are readily available online. Although you can get these fuses up to 40A, If I needed a fuse larger than 30A I think i would use a Maxi-fuse. These typically come with 8AWG wire.

RE: When will the 2020 Ford Super Duty show up?

For some reason, the 2020 HD are coming out slow. My gut tells me they don't want to rush the 7.3L and 10 speed combination. These will become "killer" sales leaders for HD pickups, Class C and Class A.

RE: Tow Vehicle Battery and Alternator

With the entire life of a Lead/Acid battery between 12.0 and 12.6, and peak charging limited to 14.4 (or .6), there is no room for voltage drop. So a huge alternator will be a lost cause even if you run welding cable from the alternator to the house bank. First, it takes AT LEAST 13.2V to put energy into a lead-acid battery, PERIOD ! I have mentioned this in a least a dozen other posts. Modern cars, light and most medium duty truck (Class A) use "smart charging". In short, the voltage is regulated AT THE VEHICLE BATTERY to about 13.2V for 99% of the time the engine is running. After the voltage drop to your house battery bank, there is simply not enough voltage left to charge it !

RE: Tow Vehicle Battery and Alternator

I know I can install a DC to DC charger in the trailer. Do this FIRST ! Use the standard 12V line on your pin trailer harness. I think you will be surprised at how much better it works. Whether it can completely recharge your battery bank depends on 1) the size of the battery bank, 2) the "state of charge" (SOC) when you hit the road and 3) how many hours you drive.
