There's a lot of variance in ramps, etc., but you shouldn't have a problem. We used our 26' Class C to launch an 18' Sea Ray & then a 32' Aerbus to launch our 21' Sea Ray all over California & the Colorado River. Unless the slant of the ramp is ridiculous, neither lack of power to retrieve or getting the coach in the water to launch should be an issue. I loved that the rear wheels were high & dry. Any ramp I would have been comfortable using either of our full size Ford vans or our Tundra, I would have used either RV on. I would caution you about two things. Ramps that are long and steep necessitate that you go down them very, very slowly. (Seems obvious, right?). And many boaters will drive forward until close to the end of the ramp, then do a U-turn and finish backing down. Don't want to do that in a motorhome! Anytime I was at a new ramp, regardless of what I was towing with, I watched others launch & retrieve to see what idiosyncrasies the new ramp had. Learn from the mistakes of others!
