Dave i feel for you that your RV is back at the dealer....ours is a year old and has been back twice! and needs to go again

as well as i have had mobil service men out...i went from a entery level RV to this one and i amnot sure it was the best move sometimes.....and we are not alone. Our co worker has a Carriage the high end on and his has been in the service for two weeks now.....BUT i do know a GREAT service man in texas if you ever need one! LOL thanks for the input.
Can i use a vaccumm up there????
