I don't think you would be able to tow a Fifth Wheel, the bed is too short... they do make Fifth Wheel hitches for a short bed pickup, but you also have the narrow issue. The shortbed ones are very, very pricey, they have a mechanical system that you activate before making a turn and slides the load back to kind of teetering over your (always open) tailgate, then draws it back when you straighten out... generally, buying a different truck would probably be cheaper.
The problem with a short-bed is when you turn, the the fifth wheel would smash into the back window of the truck...
You have a second issue with fifth wheels... the bed weight. The old small ones might not be too bad (but definitely pay attention to it). We've been planning for retirement a few years out, and I noticed that even the smallish 35 foot ones (small in 5th wheel land) are something like 2400-2700 lbs of bed weight... definitely more than the little Colorado can carry. I haven't been planning to do so though, I have about a year left on the least, I'm planning to turn it into a 2500HD D-Max for the retirement traveling.
I suspect you will need to stick to the travel-trailer type setup w/ a weight distribution hitch.
