I recently purchased a travel trailer that I tow with my 06 V8 hemi Overland. The issue I'm having is that the battery in the trailer is not recharging while plugged into the truck and being towed. I've swapped out the battery, hoping that's the issue, but no dice. The RV store says it's probably the fuse that blown and I should check that. The problem is that it's not clear which fuse charges a tow battery. The manual clearly shows turning and stopping fuses for a trailer, but not the battery. Any help?
