When you find a design you like based on floorplan and size, take to the web, RV trader, RVT will have listings nationwide for the same units. It's natural to go to the ones that have a model listed the cheapest, but when you get in there you will often find that they charge high destination/delivery fees, large prep fees etc. Most dealers have websites, and if they dont charge all the BS fees they are quick to point it out, note their pricing and then use that to compare to the ones that do. $1000 sales price more from a no fee dealer beats heck out of the guy thats $1000 cheaper but then charges $450 administrative fee, $2000 dealer prep, and $1700 delivery, and yes there are some that will tack all that on a small TT.
Search everywhere you can till you find what you like, and then use the power of the web to visit all the dealers sites to get the true best deal for you.
