Go to some shows and showrooms and look at as many rv's as you can. Don't rush. Try to picture yourself and family staying in each, what you will be doing and how, where you will store things, etc. Once you have an idea of what you want, then you have to see how you can get it withing the funds available. Remember, new units depreciate the moment you sign the papers and drive them off the lot. So you may want to start used or low end till you have a feel for what it is like. As Gary above said, you probably won't get it "right" the first time around. We didn't, although we certainly have enjoyed each rig we had. So I wouldn't overstress myself about it either. If you find the absolute perfect one the first time around, wonderful. But be prepared that you may later want to "trade up". When we bought our first rig, the salesman said, "I want to treat you right because I know you are going to love rv'ing and that you will be back to trade up."
