Dynamax is a subsidiary of Forest River. The Rev is of nice quality, but not as high quality as their other motor homes. But of course it is a value line product, so that is to be expected. We've owned ours for about six weeks and so far we are very pleased with it.
Pluses - Good gas mileage (getting around 13 mpg including frequent trips into the Blue Ridge mountains), very maneuverable, perfect size (for our needs), comfortable ride, fantastic beds (but we had custom made mattresses added to replace the cheap ones that were supplied), excellent value, no need for a toad, I fit in the shower and don't bump my head on anything in the coach, excellent driver legroom.
Minuses - Can't park as many places as a Class B, Rubber roof (as already pointed out), only 2,000 lbs tow capacity (but that is not an issue for us), small living space (the trade off for having wonderfully comfortable beds), indoor TV is not in best viewing position (but we love having the outside TV as well).
After researching for over a year, and getting frustrated at not finding a more affordable motor home designed specifically for a couple, we were thrilled when the Rev 24TB model was announced. For us it struck the right balance, and so far we are quite pleased with our purchase.
I wish you the best in finding the perfect motor home for your needs!
