I wasn't aware of how many different motorhomes Thor was marketing as RUV, their first were the Axis line, small and not so small A models built on E-350 or E-450 bare chassis, 12,000 and 14,500 pounds respectively; lightest F-53 is now 16,000 pounds rating, I think.
Compass and Fuse are just medium size Cs at 24 feet, on 12,000 pound T-series. That's not particularly small, as 10 years ago manufacturers were offering C's as short as 19 feet on the10,500 GVWR version of the E-350 and even smaller C's on VW's T4 platform.
I don't think you'll be seeing Winnebago calling the Fuse a RUV, as the term is a Thor marketing term. Winnebago never adopted "B+" which was initially a Gulfstream marketing term.
I think you will be seeing these pulling toads, and not pulling toads, just as you see with older C's this size. It is not so much a matter of size, as I know a couple of people who use Winnebago Rialtas (22 feet, just under 7 wide) as their only vehicle. They are no bigger than a long-bed dually pickup or a farm stake truck.
Pulling a toad is more about not wanting to break camp to go somewhere. I pull a toad when that is an issue for me, but don't when road tripping. My C is just fine for getting around most of the places I go, even at 30 feet by 8 1/2 wide; but I don't try to get around in densely populated cities or even suburbs where parking is at a premium. In those places, 24-26 feet and 7 wide could still be a problem, not moving around, rather parking.
