Boy you're an adventuresome type. Picking up a new unit and immediately leaving on a long trip??
I remember when we picked up our 2007 Eagle Model 322FKS Trailer and took of for Cape Cod. Stayed at a campground by Plymouth, Mass. and and blew a fuse, in the electrical panel. Stove fan and kitchen sink light wouldn't work. Got back to Michigan and the dealer traced it to a short in the exhaust fan switch.
I can see now that you're going to have a wonderful future in camping with your attitude.
