I didn't feel it was that hard. I would get on the roof, unroll enough so I could drop it down the back, even it up on the sides and then start working my way forward. Final evening up was done on a step ladder. I was able to do all it all solo.
There are two weighted straps to clip in to toss the straps under the trailer to the other side.
I am now putting on a cover for a 26 ft trailer and still able to do it solo.
Hope that helps
