From our experience all depends on the person and trailer.
My wife and I are soon to be on our third short bed truck for a fifth wheel but our 5th short bed truck over all.
We have had a 2012 Ram Mega cab towing a 40’ bunk house and a 2016 Crew Cab Cummins towing a 42’ fiver and are ordering a new 2019 Mega Cab dually Cummins. Out of the 2 other trucks we have always had a sliding hitch, but never used it.
Our trailers are the new front cap design that allows tighter turning. So with that and my wife who is an amazing spotter never had an issue. We have managed to get it into some good spots. We had an issue once so far that took several tries and that was at Fort Wilderness in Florida.
With the 2019 we aren’t even doing a sliding hitch.
But again a good spotter and communication is key.
