Simple Guy Looking for Simple Truck Camper (Short bed)

So I bought the longest receiver that i could from etrailer for my weight distibution setup. I found one that is 14 inches long. With my tailgate down the truck wont hit the trailer and i turned it all the way to where trailer tongue hit the receiver. Does this mean I can get an 8 foot long camper and be okay of clearance with my towing setup? Curious how long I can go especially since the camper is wider than my tailgate. Hoping to leave tailgate on at this point.

Let me know if you need more pics or if you cant see them. I tried to post the pic of the trailer tongue hitting the receiver but it seems to have an error every time.
