We're going to buy a 36-40 Diesel Pusher this spring, and need some advice. I've been searching all over the internet for various coaches, and have pretty much narrowed our search to Tiffin, Newmar, some Fleetwood models, Monaco,and Holiday Rambler. Should I favor Dealerships over Private Parties or vice-versa? Are there any Dealers that are particularly favorable ? It looks as though the Houston area has a large number of Dealers. Are there other areas of the country where I should look ? Any thoughts regarding companies like "Best Pre-Owned RV's" or "PPL", or "Lazy Daze" ?
