If you have a TS3 then call Hensley and ask for a Simple Slide for it. It allows you to manually release the TS3 to move the hitch rearward. Otherwise the TS3 will mount in Standard rails in the bed of your truck.
I agree with the slider since the OP has a short bed.
I have a short bed and slider (Reese) . . .
I have not yet used the slider function, but I am glad I have it for when I will need it.
I've made some pretty tight turns without issues, but I've come close a couple of times to making contact, despite having the 88* turn radius on the Prowler.
I plan on using the slider function more this next camping season, especially when I back the trailer in our side yard as it is a pretty tight back-up.
