I just purchased a new 2014 Tiffin 34 TGA. Prior to buying I talked to both RV Corral and BYoung RV. Per recommendations on this forum I contacted Sherman RV in Sherman, Ms. Sherman beat the local rv dealers best price by about $20,000 (approx. 28% less than MSRP). I also financed through them for a better rate than I could get locally.
The people at BYoung and RV Corral seemed nice enough (although RV Corrals salesperson wasn't good about returning calls when he said he would) but they couldn't come close to the deal I got in Sherman. When I picked up the motor home it had been completely prepped and the tech spent a full day walking me through it's operation. There were no added fees or costs the total price of the motor home was the price originally quoted. The actual in person sales transaction took less than 30 minutes.
They allowed us to stay on their property and said we coud stay as long as we wanted until we were confident everything about the coach was right. We could not have asked to be treated better or more fairly.
We didn't have a trade in so I don't know how, if at all, it would have changed our experience but calling Sherman and asking for a quote was the best move I've made in quite a while.
Good luck!
