RV Camper = works on AC...not on DC?

[FQ2]

Rv works on AC but not on DC.

Batteries are fine

fuses are all good

It'a a 5 year old Gulfstram Amerilite


what am i missing here?

I had that problem on my trailer before, it was the battery even though it seemed to check ok with a voltmeter.

I suspect battery as well, get someone to load test it,

Test for DC power at the fuse box could be a fuse between the battery and fuse box mine does have one.

As Bat119 said, look for main fuse between battery and fuse panel. This can also be a little circuit breaker that can trip of be faulty. I had a buddy that had this issue and his was hidden under a little panel within the underbelly of the trailer which was hard to find. We got rid of the circuit breaker and put in a large fuse holder with a fuse instead, less problematic.

Check battery cables at battery. Tug on cable a bit. They corrode easily and can look like they're in place properly when they arent.

Check fuses and insure main breaker switch is in on position. It happens

Check small circuit breaker. Usually near battery on frame. They can become corroded.

This is likely your problem.
