Yes, that’s why they put a ladder on the back. I’m 220 and go up there all the time. I walk softly but Jayco has one of the better roofs in the industry.
Same here. Plenty strong enough. One helpful thing to remember is check the bottom of your shoes for stuck stones. They can damage the roof if you don't pick them out.
I am close to 200 and have had no problem. My one word of caution is to use the ladder properly. Keep as much weight as you can vertically and don't yank on the ladder while climbing.
