In 15 months of RV shopping I drove at least 3500 miles to visit three manufacturers and at least 10 RV shows.
If you don't know what you want, it is worthwhile making trips to large RV shows. Houston has one of the largest, and is not all that far away from you; I made a 10 hour round trip to the KC show to meet the nearest dealer for a brand manufactured in the Northwest. If think you know what you want, and a dealer has it, it can be worth the trip even if you learn that this is not really what you want.
