Battery Recommendations

Just recently ordered a new 16 Pinnacle 38FLSA to replace our toy hauler.
Any thoughts on how many batteries to install. In the past we have only had two. In the new unit there is space for six. Six seems to be allot...

I was thinking that if we had four installed it would increase our run time on the inverter to run the residential fridge while in travel mode?

Any thoughts or opninons would be greatly appreciated.

Welcome to the forum. You came to the right place for information and hopefully give some back. The 38FLSA is what DW and I want next, just need to upgrade the TV first.

Not knowing anything else about your needs, I would go with at least 4 Trojan T-105 (6 Volt) batteries.

If you like to dry camp, I would recommend going with 6 T-105 batteries. Which ever way you go just make sure that all the batteries manufacture dates are the same or within a month.

You will probably want to replace the wire from the TV to the TT with a larger gauge wire, it increase the amps coming from the TV.

Just remember you will need a way to keep them charged. Keep us informed with your decision.

Your truck will run the fridge while driving. Like mentioned if you dry camp a lot 4-6 would be needed. If you dry camp where solar would work then if it were me I'd get 2 for the fridge and 2 for the coach. Run the solar to keep the batteries charged. Most only seem to get a few days max out of 2 batteries with a res fridge. A generator would help too.

If you stay at elec sites mostly then it doesn't matter what you do.
