I pull a 38CK with a 3/4 ton Chevy ext cab. As tight as the truck will turn going forward you can't make the trailer hit the truck. Backing up will allow you to jackknife the rig and damage both the truck and the trailer. A slider allows more jackknife but you still need to be careful. Also depending on your pinbox and hitch setup, you need to be careful about the pinbox hitting the tailgate or bed.
That said, I recently made a hard U turn in a campground on uneven ground and gouged the trailer cap and the roof of the truck as well as destroyed my rear glass.
