Ok this may be a stupid question. I know people have to be able to get on top to work on the a/ c units and what not, bu5 just how much walking around can/should be done up there? Btw we have a 2020...
I get up on my TT frequently to check things. I try to walk on the rafters instead of between them. After a while you can see where they are. Until then you can use a foot to feel where the rafters run.
