I have a short bed Dodge 2500 and pull a 30' fifth without issue. I do have a Pullrite Superglide auto sliding hitch. During a turn the hitch slides back allowing for very tight turns.
Many use a manual slide hitch. In the normal tow position the turn radius maybe limited depending on trailers front cap design. This is normally not a problem as most rarely need to turn sharp while towing. Once to a campground, the hitch is manually slid to a rear position allowing full 90 degree turning while backing into a spot.
Others have used a standard non sliding hitch with the newer angled front cap trailers without issue. In theory you can turn up to 85-88 degrees without contact. Since most never turn that sharp it works for them.
That said, the Pullrite Superglide makes it fool proof if in doubt. It is more expensive than other hitches but takes the worry away. I prefer the short bed myself but thats another argument!!
