Walk on roof of 2003 Thor 187TB?

[scrappymcnugget]

I've got a 2003 Thor 187TB toy hauler. I'm doing some roof maintenance and I'm wondering how many people walk on these roofs. I have not, but may need to someday.

Thinking about using a plywood sheet to disperse my weight? I see people walking on rvs all the time on other RV's but I've looked at the framing in mine and seems sketchy, even without age.

Does anyone have this model? And/or method to reseal roof things?

Thanks in advance. Sorry, I'm a noob

Welcome aboard!
If you treat walking on the roof in the same manner that you'd treat walking on VERY thin ice: you'll most likely be okay.
But since you're already aware of what is underneath the roof: treat it more like trying to pet a rabid wolf...
