I have a Class A now and was wondering about this very issue. How much more work is it to set up a 5th wheel? Is leveling a chore? Is a 5th wheel still cheaper if you have to buy a new truck to tow it? One distinct advantage I see is if you get a small enough 5th wheel(28 ft or less) that can be towed with a SRW truck you can always use it for a second vehicle.
Setting up a 5th wheel is more work than a class A.
Just hitching and unhitching is more work.
Class A offers push button convenience a 5th wheel requires a bit more interaction than just pushing a button.
In and out of the truck to back up/pull forward etc. when hitching. Raise gate lower gate, There is just more to do.
