Shopping for a 3/4 ton, What fit issues should I expect?

It's been said before...but I wil say it again...get a one ton. I currently have a one ton dually. Next truck camper will be a pop up variety but will still get a one ton single wheel. Having had half ton, 3/4 ton, one ton, and a one ton dually..I wouldn't have less than a one ton. Gives you more capacity and one can't have too much truck. The side walls of the beds are getting crazy tall but building a small spacer for the camper to ride on is not a big deal. Enjoy!!!
