Are extended service contracts for new Class B motorhomes a good idea? We have a one year warranty on coach, 3 years on chassis. The dealer is trying to sell us an extended service contract for $5500 for 5 years, including SafeRide RV Motor Club roadside assistance. We have three days to decide (new Coachmen Nova Li3 RB) so are soliciting opinions (and experience). First time motorhome owners. Lots to learn. Thanks!
