I had a great experience with La Mesa RV when I purchased my camper van. Although I bought a used van, I started out looking at brand new. The sales rep was very patient with me and it wasn't a quick decision at all. It took a few months before I finally decided on what I wanted and the sales staff was great. No real pressure to sell and they called a couple of times to let me know that a vehicle I might be interested in came in.
I had a great experience with them and I know other's that have had the same. Definitely recommend.
