April 24, 2010I just bought an 18` 5th wheel camper. I am new to the 5th wheel world. I`m about to remove the extended box king pin and construct a goose neck coupling. My question is; how much clearance from the top of the bed sides on the truck to the bottom underneith of the cab should have? Right now with the camper level I only have about 2.5" "If I use the 5th wheel hitch not a gooseneck".
The truck is a 2003 2500 4X4 reg cab 8` bed. Camper is 18` tandom axle.
Thanks for any help.
