I have a 2004 Coleman Bayside Elite. We took it out for the first time this weekend. When at home and plugged in to the house all of the outlets worked. I was able to run the AC and use the outlets. We get to the campground and plug in to 30 amp and only the AC outlet and the lights work. We reset the gfi outlet and that tripped power to the whole camper at the power box. My brother who is an electrician has no clue. We ended up running an extension cord and using a power strip but that will get crazy annoying if we have to do that every time. Any ideas about what could be going on?
