I have the same truck and use a Curt Q24 hitch and have never needed a slider. If I tried to turn any sharper than 88 degrees the pin box would hit the truck sides first anyway....I'm getting ready to do this right now . . .
We are moving up to a 5th-wheel next week and was advised to get a slider for my 2015 Chevy Siverado 2500HD shortbox.
We worked it into the deal . . . but still not too late to change!
If I were not to get the slider for our new Heartland Prowler P292 . . . what should I get?
Maybe I should start a new thread with that question . . .
