Good Luck on you trip, Love our 3100 and we're getting ready to head west this fall for a 2 month trip. Already have 25000 on ours and no real problems. The one big one was the Generator, had bad fuel pump with 2 hrs on it, so run the Gen for a while before leaving. Was a manufacturer problem at the time, so should be fixed. The best thing is to have fun
