New guy here and new to travel trailers... so my new to me travel trailer came with dual 6v batteries in series so 12v... im on a very tight budget being on a fixed income, what would be the best way...
I'd say depending on where you're located in the States, 100 watts solar minimum, with controller & batteries fully charged from the start. Which then also would be useful when dry-camping.
Otherwise, get a portable "Smart" battery charger & keep them at home when not in use.
