A friend of mine's son weighted just over 500#. He lost his job as a truck driver because he kept bending the stairs on the truck even after the trucking company had moved his seat for his stomach to clear the wheel. He wasn't that heavy when they hired him ( 275# ) but when he continued to gain weight they asked him to lose some. All that did was make him bitter. After losing his job he eventually fell thru the floor of his mobile home and had to call the fire department to get him out. If a mobile home couldn't hold his weight I have doubts that a travel trailer would hold up the weight of your friend.
