I'd suggest you get a little more specific about what you're looking for. I currently have a 32 1/2' class C which has so much more room than my previous 24' class C. The 24'er could/would go anywhere you could/ would take a normal size car or pick up truck. The longer MH - not so much. On the road they drove the same, but maneuvering (U turns for example)they are different.
I don't think you'll find many chair/table combinations in a smaller c (if that's what you're looking for) most will have dinettes.
Is there a length limit that your wife would be comfortable driving ? My wife hasn't driven any of the RVs I've had, since my first 22' class C back in the mid nineties.
