Welcome Huron. RVs are not like cars in that you do not need to buy from the local dealer. Don't take any cr@p, excuses, or bad behavior from any of them. You are the guy with the money, so spend it wisely at a place that treats you right.
If you are new to RVing in general consider a couple of things before you buy. One thing is to visit a Large RV show, with many dealers, NOT a show put on by one dealer. For example, in mid-September, there will be a very large show in Hershey PA, self promoted as the largest in the country. There you can see all types of RVs, floor plans, and eye-candy. They will even let you test drive one there (at least they did the last time I was there). Further, if you are sure of what you want, they generally offer show prices. Other large shows operate the same way.
Second, consider renting a Class C or TT for a week or week-end to try it out. See if you really like the life style. See if the family can tolerate being in a box with each other for periods of time. See if you like handling sewage every few days.
Best wishes with your search.
