I would like to see "SCVjeff" and "Dodge guy" tell the guy in the one rv park we where in that his roof was strong enough to carry his weight and it collapsed when he got on the roof to the point that the unit was a total acording to the insurance company, trailer was a 2012 pull model year the guy was 145 pounds, his trailer did not come with a ladder, my friends 2004 trailer did not come with a ladder and the manual stated that it was not meant to be walked on it at all.
Some of the persons that wash RV'S look for ladders to see if they can get on the roofs, if no ladder they use step ladders on the side of the unit to wash the roofs with out getting on the roof at all, they are not dumb if they damage a roof because it was not accesorised for walking on the roof.
Some pull trailers are not the same as class A or class C or 5th some units are not as well built as others you need to be aware of what you can do and can not do up there.
Then of course it is not my dime, I can have more that four persdons on the roof of my RV.
