Soon I will be purchasing my first RV. I will be traveling with my sister sometimes, my sweetheart some, and by myself occasionally, for a total of 4 to 5 months total per year. I seem to find a lot of used Winnebagos and Fleetwood in my price range ($20,000) but I consistently seem to fall for the Newmar! My sweetheart is concerned about parts availability, as he is a shade tree mechanic, and can do a lot of maintenance himself. Generally speaking, do service dealers work on Newmar as easily as Winnebago and Fleetwood? Are parts more expensive for the Newmar than for others? My budget is around $20,000. Should I go with my instinct and look for an older Newmar in my price range?
