My experience has generally not been quite the same as some who've posted on this thread.
We made our first, and so far only, RV TT purchase in 2010. We did buy used but found a very nice 3 year old TT. A bit on the heavier side with a slide-out but it fits us well. I wasn't worried so much about depreciation of why we didn't go with new, what concerned me was not knowing was price to settle on when buying new so as we didn't get taken advantage of. Biggest advice I can give is be very contentious about floor plan to make sure it fits you and then go with a decent build known for quality.
Now that we have been doing the RV thing for 6 years, I feel very comfortable with moving forward trying to work out a deal on a new RV when we choose to sell our current TT and go to a truck camper in 5-6 years. What I haven't seen mentioned in any of the previous posts is what price to go for on new RVs. What I have gathered over the last six years is that many, many people recommend buying new RVs at about 65-70 percent of the MSRP pricing. Keep in mind there can be many factors as to if you can do this good, or even better, but that is what I would shoot for probably offering 60 percent of the MSRP for my first offer and then work from there. Of course timing, demand, new models, ordering a RV, stock on hand all play into what is the best deal you can negotiate on a new RV. Used will be a bit harder to understand current market value as it will be hard to find an exact like for like RV, in you area, for true price comparison. As in any price negotiation, don't get emotional.
