Thanks turtle n peeps. I have discovered one other thing that might explain. From the positive terminal, one wire goes into camper, another wire is route outside the bottom of camper almost all the way to rear bumper and its cut and taped. Have no clue what it went to but it routes over one of the crossmembers and is pinched. Looks like it may have worn insulation off and that could possibly have created a ground condition for the + terminal snd caused dead short. It is a huge wire. Any clue what this would have routed to? Really strange b/c its the same guage wire that is routed into camper. I'm 99% sure this wire is grounding out! Wierd...
