Bird,
We purchased our Pup there 2 1/2 years ago and they were great. Since it is about a 3 hour drive home, we had reservations at Flamingo for the night after we were picking up the Pup, but there was a problem they needed to fix and the person that does the work for them was out of town so they would not be able to get to it that day. They pulled a TT out to the park for us to stay in that night, paid for our dinner, and then delivered the Pup to us the next week after the work was done. We did out second walk through with the delivery driver who spent about 2 hours with us making sure we knew how to set-up and operate everything.
It was a very positive experience from the looking part all the way through the purchase. Never any pressure and what I felt was a fair deal without having to spend hours haggling. We recently stopped in to look again and again felt no pressure and received all the help we needed. I definitely recommend them for the sales part. We did not use them for service (haven't needed any) so I can't comment on that side of it.
