06 Charleston walking on the roof

[wtbuck12]

Wondering if anyone could give me some feedback. I have an 06 Charleston 400qs with no ladder on the rear, and was wondering if I could safely walk on the roof. I am kind of a heavy weight at 270 lbs. I need to clean, seal and check the seams, but was concerned about walking around up there. Should I get someone small to go up there or can the roof handle my weight?
The specs say I have a one piece fiberglass roof, but there is a rubber roof and I was wondering if that is normal to have rubber over fiberglass? My previous motorhome was a Holiday Rambler and it had a fiberglass roof, but no rubber roof on top.

Your rig having or not having a ladder is not an indication of roof strength. There are many articles in the library about walking on a roof. What many folks that are heavier have done is to make some strips out of 1/2 ply 4'x8" or so to lay on the roof and walk on to distribute the weight. if you want to save yourself the risk of the climb or a fall having someone else smaller may be the way to go

Thanks for your response.
I have read several of the posts on the roof and ladder and understand that the ladder is not an indicator of roof strength. I was just hoping someone had experience with that particular MH and could give some feedback
