First thing is to enjoy the Tampa Show it is the biggest. Ask the factory reps whatever technique questions you have as they can generally answer them better then the sales people. Most if not all of the brands have reps on hand. Your ticket is good for two days and to take in the show, RV's, vendors, seminars, etc you will need that time. Most of the major brands from low to high end have most of their models on display. You can kick the tires etc and get a good feel for the rigs. I would not buy a rig at a show for all the reasons listed already. Good luck have fun it is a great show.
