Our home base is 30 miles from PIR, the location of the Good Sam Rally, so we attended, bought a day pass. We were interested in looking at new 5th wheels, but we were very disappointed. The RV mix was mostly Motor Homes, and not so many 5th Wheels and not so many Travel Trailers. We walked past all the vendors, but did not buy anything. Everything I saw I can and do buy online, generally for less money. On the plus side, the venue was very nice and it seemed very well organized.
It is unlikely that we will ever attend a Good Sam Rally again anywhere. The previous weekend, we went to a free RV show at the University of Phoenix stadium in Glendale, AZ, home of the NFL Cardinals, and venue of the recent Super Bowl. It was put on by LaMesa RV, which has two retail locations here in the Valley. There were a LOT more RV's of every type on display there than at the Good Sam Rally a week later, and as I mentioned, it was free. There weren't an overwhelming number of sales folks either, so one could look over many RV's and seldom be pestered.
