We went from a tow behind Cougar 24RKS to a Cougar 279RKS fifth wheel. Towing is much better with the fifth wheel, backing is trickier, much more storage capacity in the new rig, and I've only forgotten about the steps (in the dark) once. There is a bunch of room in the fifth wheel that we didn't have before, and the rear kitchen is very nice. We have an Andersen and haven't had a turning problem.
On the flip side; height of my truck ( 2016 Ram 2500 Hemi), has been an issue, and the height of the trailer has to be considered when in campgrounds, etc.
We've towed the trailer over 10,000 miles (California, Alaska, Idaho, etc) and would buy another fifth wheel.
