one thing I havent seen mentiond is storage. My parents have turned into snowbirds and sold there 5th and bought a 42 foot diesel pusher and a small honda to tow behind it. we were talking and I asked which one she liked better. she said both. she said for going to one place and setting up home the motorhome is better. they have a small car for driving around arazona for 4 to 6 months of the year, but she misses the storage of the 5th wheel. the motorhome has lots of storage also but a large amount of it is only accessable from outside where the 5th wheel has way more interior storage. but she realy liked being able to go to the washroom or grab a pop out of the fridge wheile traveling with out having to get out in the motorhome.
now days with the auto leveling system on 5th wheels there is realy no advantage to setiing up camp with a motorhome. still have to unhook your towed to get in a site, actualy I can set up twice as fast as my parents with my 5th wheel.
