I don't usually agree with Grit Dog, but in this case I'm in 100% agreement.
It is highly unlikely that someone else has your exact rig, or knows offhand if it fits.
You've got the truck, you've got the camper, and you've got nothing to lose at this point. All you need is a tape measure to figure out what you'll need to do to make it fit.
If the camper won't clear the cab, build a platform. The only other issue you may have is with the tailgate opening at the rear of the bed. On some brands they narrowed the tailgate opening and rounded the corners, so any "bump-outs" that you might have in the floor past the wheel wheels could interfere there.
