Welcome to the forum!
There's an old saying about this sort of thing: "They're plenty strong enough: until they aren't!"
IF you decide to go up there for an eyeball full: no shoes!
Spread your weight out
just as if you were on VERY thin ice.
At 195 lbs: I'm honestly not 100% comfortable in climbing up on my own RV's roof.
But I sell insurance; so that's just me!
