350 lbs and 6'5". I really like those stabilizer jacks for the steps. My steps groan a bit but I keep an eye on them and they seem really sturdy so far. I can sit at one spot at the dinette table. Not so much getting in, it's getting out! My TT has a nice couch that I kind of take over! Had to add 2X3 strapping under the queen bed because I broke that thin wood right away. The bunk beds in my camper are way better built than the queen bed and could hold your weight no problem. Pay attention to Gross combined weight rating as it normally assumes 150 pound driver and being over that affects how much cargo you can carry. Finding a decent camping chair is a pain!
I suggest you go to RV shows and ask the sales teams there about accommodating weight and then follow up with wandering around a few. You will be able to tell if they are bs'ing you if they squirm when you go near their rigs. If you want to avoid the rush, go during the off peak times.
Find your rig. There are many to choose from. See you out there.
