[SOLVED] Work truck with service bed to tow a fifth wheel?

AS suggested Above^^^^

And it being a Dually should not have issue with 5th wheel WET pin weight

Yeah, get rid of the boxes and go flatbed and you would be pretty well setup. Regular cab can be a comfort "challenge" though. No room to slide your set back and no storage behind you. It will get the job done but it will feel like you're driving a Uhaul truck.... everyday.

Sell the utility bed and throw on a flat bed setup to tow a 5er.

Full disclosure- I'm not a fifth wheel guy myself. One potential issue I see is that the sides of the utility body look taller than a typical pickup bed which could lead to clearance issues with the trailer. Raising the hitch itself could allow for clearance, but that then creates problems with the hitch being too high to keep the trailer reasonably level while towing. But if the truck in question is clean, reasonably priced and otherwise capable, removing the utility body and replacing it with a flatbed or fifth wheel towing type body might be an option.
