Weight on a Class C roof

[EdTheEdge]

Hello, This is my first post on these forums. I am not new to RVing as I have owned an rv since June 2013. I bought a Thor Chateau 22e new at that time. I go out once a month at least but more often twice a month. I love RVing but even after 4 1/2 years of using "HaRVey" I am still learning things. So here is my first question:

How much weight can a Class C roof withstand? I am 6'4" and weigh 240lbs. I would like to climb up on top to do some maintenance, mostly to wash the roof and clean the fan housings but I fear that I may be too heavy and dont want to damage anything. I'm a very cautious guy so I wanted to ask the experts here before I venture "up there".

TIA,
Ed

If what you need to reach cannot be accessed from a ladder on the sides, you can use a small (4'x4') piece of luan or plywood to spread the weight over a larger area, but with the manufacturers constantly looking for ways to build these units cheaper and lighter, I would try to avoid too much time or movement especially on any manufacturers entry level product lines.

I thought of using something to spread the weight around.... I was also trying to avoid purchasing a taller ladder. I have a 12 footer and it's not quite tall enough to reach were I need to reach.

By "not quite" if 8" would make the difference, and you have a solid , flat surface, put a concrete block under each leg.
I even used a picnic table once and put a ladder on it to get on my old "C".

WOW.

WOW Indeed.......
Perhaps a handle change is needed to Edlivinonedge?

Somebody call OSHA LOL.

Not to answer “flippantly”....but it depends upon the class c. As with all rv’s, there is quite a range in materials used. We have an older Bigfoot....and the roof is quite rigid. I’m 6’ at 200... I can “barely” detect any roof flex! If you can find any manufacturers specifications, they may offer some guidance as to the limitations.
