I'm the original poster, and yes, we do have a TT. But the weight considerations are the same, I'm sure, no matter what kind of RV you have. The problem with the TT is there isn't as much basement storage as a 5th wheel, so we have to think about where to put the heavier items. And one poster mentioned the weight distribution from front to back.....very important. We recently had our TT with its contents weighed at a truck stop. Our problem was from front to back, so we now have to think about redistributing the weight for our upcoming long trip.
I love the suggestion about velcro and maybe even mini bungee cords to tie the handles of the cabinets together. Right now our cabinet doors fit rather snugly, but after a trip across country things may work loose, and it may eventually become a problem. Not a bad idea to devise a way to prevent the cabinet doors from opening.
Thanks, everyone, for your input. We'll know a LOT more after we return from our first long RV trip. It will be an adventure......and a learning experience, I'm sure!
