Ok guys, we just bought a used truck camper today

. I want to know what kind of frame mounts you guys suggest. I was looking into the torklift system. How do they mount in the rear factory receiver hitch? My hitch is tucked under to much for the pipe to come straight out. They would need to be atan angle to go under the box sides. Is that how they come? Anyone ever used the torklift brackets? Thanks for any help in advance!
