From our POV, it's no contest. Class A gives you a cab area that can be included in the house by turning the seats around. It has a much more expansive view from the front seats and there isn't that useless aluminum box obscuring your upward view through the windshield.
We started out with a 26' C and gave up after 1.5 seasons. Three years later we bought out present rig, which gets better mileage than the 460 with a carb, has a lot more room and is easier to drive.
Unfortunately, since we had the "C", gas has gone from $1.75 to near $4.00 and CG fees from $15 a night to over $30. A 10-day, 1200 mile trip now costs near $1000. Can't do that on a limited retiree budget, so the rig will be up for sale next month.
