You can get a Pullrite slider for the 5.5' bed.
Pullrite comes with too much of a weight penalty. If going with the 5th wheel, get a conventional hitch and the Reese Sidewinder.
As mentioned in other posts, the pin weight of the 5er is the weak link for 1/2 ton trucks (and can be for 3/4 ton trucks too!). When I was researching this two years ago, I found the Springdale 247FWRLLS to have the lightest pin weight. Good for the weight game, not so good for staying well behaved on bad roads. I keep heavy items in front of the trailer axles and still just have 17% of my trailer weight on the pin.
I'm at 90% of my GCVW and find my weak link is interstate into headwinds. The engine struggles. I also won't got to Colorado with this setup (due to lack of reserve in engine and brakes), but have more options than time to get to.
Good luck!
