I think all C class Motor homes are dully wheels on the rear except for the ones based on a Ram Promaster chassis and those likely have a very low tow rating..
I didn't know to shop floorplan first and everything else later, I bought a Winnebago View 23H, that has a cab over bunk, a jackknife couch, and the break down dinette. I started out using the cab over bunk (I am by myself) and found two or so times a night down and up the ladder was a hassle. The ladder has very narrow rungs and hurt bare feet due to their sharp tread pattern, and being half asleep doing this was, well, not the best idea.
I now use the jackknife couch, no comfortable since it is not flat, but plan to convert it to a futon bed design which some View owners have done, still leaves you a nice couch and a flat bed. Downside is teardown and make up of the bed, but if in one place for more than a night I just leave the bed made up.
Using the dinette except for kids and in emergencies is not the thing to do. I keep too much stuff on the table and stuff in the unused side of the seats. I actually have a screw in the floor to keep the leg locked in place so it won't vibrate out.
Corner bed is best alternative for one person, quite workable for two, and a walkaround bed is best for two, but wastes lots of floorspace.
