GVWR vs. dry weight

Thanks Friends. When we take our first trip to a campground and I spend the first two hours trying to back the trailer into a spot and the next two hours trying to figure out leveling and what goes where I sure hope the folks around me are as kind to us as you all are. And I apologize for all the stupid questions but I'm nervous and excited and at my age I just can't afford to make too many mistakes. My wife really scared me when she went to the 7500 GVWR trailers and locked in on those models. My ears heard her say "this one is perfect", but my mind was screaming "we'll kill the new truck! Maybe we can pack light...yeah, that's what we'll do! We'll pack light...", and on and on. Guess I should stop worrying, and I imagine I will after the TT is bought and the shakedown cruise has been completed.
