I've run into a glitch with this. If your truck has a "smart" alternator, the output is reduced once the starting battery is charged. Your second battery may or may not be fully changed by that point. Many of the newer battery isolators have circuitry to deal with this to ensure you do get a full charge.definitely appreciate your input. losing a hitch rack and gas cans on the trail would be bad, but i'm way more worried about it holding up with bumps and dips in the highway...having that come lose and hit a car behind me would be a disaster. i'm going to test it out well before getting on the road with it.
while i have you here....i have a 35ah battery in my camper shell to run lights and a small water pump. i would like to charge it with the trucks elec system and was wondering what you think about tying into the wiring harness of the 7 pin trailer connector and hot tapping into the 12v wire and using that to charge the 2nd battery.
That said, I also have a 35 Ah battery in my teardrop. It runs a few lights and a roof fan. I've never had it die for lack of charge. I had looked into a 100Ah battery to deal with a fridge. I have some doubts it would have been properly charged. In the meantime, my style of camping has changed, and the fridge has gone into the Tahoe.
