I'll add my experiences, too. I'm a highly skilled driver - but not of trucks or RVs. We just purchased a Forester 3011DS and the first place I ended up with it was a Safeway parking lot. As others have suggested, the Class C actually handles rather well for a large-ish rig. Semi-wide turns for sure.
Someone mentioned blind spots. We have a set of split mirrors and the only problem I've had was on the first drive home with a merge on my right. My bottom right mirror was not "out" enough to see all of the merging vehicles. A small adjustment and I now have no blind spots at all. Check all your mirrors regularly. Use your rear camera to watch your tow or hitch-mounted equipment (bikes in our case). Backing up is a breeze with careful use of mirrors and camera - even without assistance. I've now been in and out of quite a few tight spots.
Wind and rain: I spent three days driving in wind, and one in huge rain, all over mountain passes - steep ones - in southern British Columbia. Side wind, as someone mentioned is a "pay attention" time - - hard on the shoulders and work to hold it on the road well. You have a big profile and not much weight. Slowing down helps - a lot.
Hills at 6% or less are not an issue -- the rig stays pretty even at around 50 mph (80 kph) without use of brakes. A 7% grade starts to pick up speed. We did an 8km 8% grade that scared the crap out of me at least part of the time - in the wind and rain. Someone today (an ex-truck driver) suggested to me that I simply gear down for that kind of grade. Will try that next go-round.
Ditto for climbing hills: drop down to 3rd and stay there. Way easier than bumping up and down over your gears, and much easier to save gas. Drivers of standard transmission vehicles will understand.
The ride is surprisingly good, and in light wind conditions it's very comfortable. Easy to park in most places.
One warning: because of the long back overhang...watch out when going up short steep ramps (like at gas stations). It's relatively easy to scrape the back bottom of the coach (or mostly the bottom of the hitch). I've done that once. I'll be watching next time.
Our rig is a ton of fun to camp in!
