Hi and welcome to iRV2, Geeksquad. Had the Suncruiser been sitting for awhile before you tried to drive it home? If so it is possible that the gas is old, and also contaminated. You may need to drain and flush the tank, replace the gas and the fuel filters. You may also have a carburator problem.
I imagine the generator quit because the pick-up is raised (as previously mentioned) in order to prevent one from running the tank empty while dry camping.
The good news is: you know it runs! So this is a bump in the road that is definitely fixable..
If interested, come visit us in the iRV2 Chatters chat room. We're there just about every evening from about 8:30pm eastern until about 10:00pm. It's a great bunch of folks!
