Bumper pull camper question

[deerslayer64d]

I am fixing to build a carport , also toying with the idea of buying a camper next munth , 19'-25' . My question is how wide is a camper ? I'm building carport for my truck but if I do get a camper it will go there , I'm building carport 30'x12' , is that wide enough ?

Yes, most are 96" wide with slides in.
