Any tips for installing a cover, without a roof ladder?

The key is in the folding of the cover, spotting it correctly on the roof and then rolling it out using a ladder without going on the roof. Three years...not on roof but my TT is 7.5 feet wide, only 10’ 1” high and I have longer arms.

“My understanding is if it doesn't have a ladder that means I'm not supposed to walk on the roof” Not necessarily true. I don’t have an attached ladder...don’t want one...but my roof is walkable. Generalizations and understandings are often not correct.
