I purchased my last TT, a 2018 Palomino Puma 31BHSS, from RVW, in April 2018, in the exact manner described. Yes, in my experience, the discount is legit. Not only did they find a better loan rate than anyone I could find, but they passed a huge savings on to me. I made the 8hr drive to Ohio to purchase, because I was able to save over $6K from what local dealers were going to charge. I negotiated my whole deal over the phone and through emails, and they had the trailer set up exactly how I wanted on my scheduled pick up date. I have had nothing but great service from them before, during, and after the sale and I will definitely start with them the next time I’m ready for a new camper.
p.s. I also negotiated with Wana RV, because they have very competitive pricing as well. In my case RVW was willing to undercut a deal I had negotiated with WRV to get my business.
