50-AMP Hookup for a Truck Camper?

Sure, you can use an adapter to plug a 30 amp plug into a 50 amp outlet but that outlet is still going to have a 50 amp breaker. Just make sure your internal wiring up to the camper's breaker panel can handle the 50 amps should a fault occur.

That's pretty much what I meant by "step down" but I didn't specify what was being stepped down. Thank you for clarifying.

Great point regarding wiring. From the responses, it does seem like having a 30-amp system that can handle a 50-amp fringe case is an option....

Properly done, the RV will have a 30A breaker in its own panel.

Good point! I guess my challenge is to get it "properly done." ;)

Ooff! Point taken! Space certainly is a concern.

I don't know your current location or the location of the camper (is it mobile?) but I could help you out and help you make all of the decisions you need based on your intended use

Wow! Any input you can offer is most appreciated. Unfortunately, we are stuck in Tennessee at the moment while we replace the rotted out floor and wings. We do intend to head west but not until November / December.

Personally, I always carry a 50 - 30 pigtail adapter just to cover the situation.

Have you used it much?

the wire between the camper's internal box and the shore power breaker should be sized for the breaker feeding it, not for the load it serves. You can save weight if you want. But if the OP is rewiring the camper anyway, and anticipates camping where only 50 amp service is available, why not be safe?

I'm really unsure that to anticipate as far as hookups. My thinking, though, was: given the fact that I am rewiring the system and we want to keep our options open...is supporting 50 amps a contingency worth pursuing. I'm getting the impression that it is not.
