I agree with Ductape Dave. We went to several RV shows at Hershey before deciding on our unit. Hershey is billed as the largest RV show in the US, and based on the number of rigs there, I believe it.
Every type of RV unit will be there, except for the ultra high end $1 Million and up custom type. You can spend days there if you have the time. And like most shows, you can buy there as well. It provides a great opportunity to compare and contrast different models, and to ask specific questions. Many dealers will permit a test drive there as well.
Best wishes for success!
