A couple of suggestions when you go to RV shows:
Do not bring a checkbook. Whatever you're walking thru is not the last one ever made. It isn't even the last one exactly like that one, so don't fall in love.
Don't limit yourself to a particular type or brand. Look at TTs, 5ers, B's, C's and A's.
Whatever you're in, sit down - everywhere. Is it comfortable? Is the shower big enough to turn around in?
Ask a ton of questions, even if you think it might be a stupid one. The salesperson has heard it before.
