RE: Why do I need a DC to DC charger?

YOU ABSOLUTELY DO NEED A DC-DC CHARGER !! Now I wonder how could I survive 34 years of RVing without one? :S Because vehicle "smart charging" system did not show up until after 2001 ! (Said the guy who actually wrote some of the software before retiring !) If you just want your house batteries to not run down (further than they are), you don't need one.

RE: Why do I need a DC to DC charger?

Curiosity leads to google. And there I found this; A DC-DC charger is effectively a smart-charger for your 12V system. It isolates the house battery system from the alternator, so that the vehicle's computer management system sees it as something like a set of lights. You are partially correct ! A DC-DC charger actually BOOST the voltage that is being applied to the house battery bank to a proper multi-step "smart" charge.

RE: Why do I need a DC to DC charger?

...why would you need a DC to DC charger between truck and coach? You don't. . . . On vehicles with smart charging system that gets complicated, but to my knowledge no US build truck to date has such system. YOU ABSOLUTELY DO NEED A DC-DC CHARGER ! Prove it to yourself. Start your truck. Check the voltage at the battery. Immediately after starting it should >13.8V. Let the truck idle for about 10 minutes and check the voltage again. Probably <13.2V ! Have some one hold the engine at a high idle. I'll bet it is still <13.4 ! 13.2V - 13.4V at your house battery bank will not let it discharge but it will NOT re-charge the house battery bank !

RE: Portable Wind Turbine as a power supplement?

I wanted to ask if anyone has experience with a portable wind turbine as a supplement to solar. I totally understand that, similar to solar, it's dependant on the available wind in the area. Look to the sailing crowd ! My analysis is, that it is not worth the effort/money. It is difficult to get the sustained air flow for it to be practical.

RE: Iphone vs separate hotspot box

If you get a hotspot, (cellular modem) get one from a different carrier than your phone That way one of them might have a useable signal. Great advice ! I might also add, buy a cell phone that can make calls over the internet not just to a cell tower. IMHO, if you are going to invest in a "hotspot"/cellular modem, get one that mount on the roof. That extra 5'-6' of height might be all that is required to make a connection.

RE: lug nut socket

Both my TT and my F150 require thin wall deep well sockets. Harbour Freight had them in 1/2" drive. I also bought a 30 inch breaker bar. The darned truck requires 150 lb/ft of torque and removing the lugs after they have been on a while takes some serious pull. My 2016 Edge specifies 162 lb-ft. My torque wrench only goes up to 150 lb-ft ! The HF Pittsburgh 1/2" drive, 25" breaker bar is well worth the $20 !

RE: TT tire pressure - sticker or tire PSI?

After sitting in driveway for a year, one D rated tire blew. The replacement was E rated; however, the installer said to inflate the tire to the 80 psi on the sidewall of the new E, not the sticker which is 65 psi. So now I am confused. On a trailer, go with the sidewall rating. Low air pressure causes excess sidewall flexing which causes heat which will cause a tire failure. In your case, the additional 15 psi is not likely to cause any wheel issues. If it was an addition >30 psi, I might be concerned about the strength of the wheel itself.

RE: butyly tape for solar panel install question

A small amount of butyl tape is wrapped around the screw. If you are using sheet metal screws, the tape is applied UNDER the foot of the item being fastened. If the item is through bolted (i.e. nut on the opposite side) AND the screw head is counter sunk into the foot of the item the tape is place between the screw head and the foot. Most sailors prefer butyl tape over ANY type of caulk, because they know that they will all fail because EVERYTHING flexes ! With butyl, you simply undo the fastener, remove the butyl, clean, re-apply the butyl and reinsert the fastener. Butyl tape or even excess butyl last FOREVER if kept tightly sealed.

RE: lithium batteries and shore power

Battle Born recommends a bulk charge voltage of 14.4.

RE: lithium batteries and shore power

Lithium has it's Quirks ! Do Not leave the battery connected while stored aka Not Camping A drop in (lithium) battery with built in BMS should be ok connected to shore power while camping The info from the (battery) Mfg should specify how and when Concur ! A BMS (typically built in) is critical ! If the maximum voltage your converter can output is 13.8V, this may not be adequate. Check with the battery/BMS manufacturer !

RE: Deep cycle battery maintenance

Keeping flood lead acid batteries FLOODED at all times is the most important thing you can do. If they are on a charger 24/7, I would recommend checking the liquid level every 1-2 months, especially when the temperature is above 90F. Keeping the outside of the battery clean is #2. For MAXIMUM battery life, I believe that lead acid batteries should NOT be on a charger 24/7 ! 4 - 6 hours per day on a "maintainer" is plenty. Use a cheap mechanical lamp timer for your battery maintainer.

RE: Escaping heat next summer?

After a week here went to Curtis Michigan in the middle of the UP. I spent a couple of summers near Curtis, MI. Centrally loacted in the eastern half of the UP. Close enough to many day trips to UP highlights. Don't miss the beaches along US-2 west of St Ignace, or the Picture Rocks boat tour.

RE: Domestic electric water heaters

How about a small electric tankless like the eemax I have never heard a review that rates the adequate enough for a shower. At least not a 120V version.

RE: Escaping heat next summer?

Hopefully Canada will be open by then, so the Canadian Rockies is an option. MN or MI upper peninsula are usually cooler in summer, but there is not a lot to do up there as far as "touristy" type things.

RE: RV Water heater

Speaking for myself, I turn it off at night so I don't have to listen to it run. Chatting with my daughter yesterday (her family has camped close to 50 nights this year), she said the same thing and added how LOUD other campers water heaters are !

RE: AGM upgrade

I did add a cheap (China) monitor with a shunt to check voltages and amps. As long as it is "reasonably" accurate, then it is worth what you paid for it. !

RE: Domestic electric water heaters

Suburban and Atwood have both proven to be very good and highly reliable water heaters. Good to get positive feedback ! My daughter's Attwood never has run right since the first day the bought their Jayco. It would light once, but almost never re-light until you cycled the power switch. 3 trips back to the dealer and over $100 out of pocket for "igniter adjustment" and they gave up. If they want hot water, they have to keep cycling the power switch. Very strange.
