Two people will make the job easier, but I have done mine by myself before. Really not that difficult. Just roll it out on the roof and drape it down the sides and ends. Then it's just a matter of running the straps underneath and connecting the buckles, and securing the ends. Be sure to buy the right size for your camper, and the rest is easy. If you don't have a ladder on your rv, one is all that is needed. I do mine using just the ladder attached to the rear of my camper.
