The real determining factor between a 5th wheel and MH is how they will be travelling.
A MH is best for long drive times and short stays...Drive 400 miles stop overnight and drive 400 miles the next day and stop for two days. You can always tow a vehicle behind the MH for side trips.
A 5th wheel works better for long stays more livable space than an equal sized MH. In a MH you lose 1 to 3 feet due to the dash area. Like others have said, a generator equipped 5th wheel will allow the 5th wheel to be cool when you stop. We stop about 1/2 hour from our destination to start the genrator and AC so the coach will be cooled down when we arrive. Hitching unhitching becomes second nature.
Either a MH or 5th wheel works no matter how you travel and both have pros and cons so it boils down to personal choice. You see about a 50/50 mix on the road and in RV Parks.
