OP: I think you may be trying to 'oversteer'. When we got ours new, the salesperson took us up a curvy mountain road. Right away he said "you're oversteering, just put light pressure on the wheel and plan for your next turn beforehand and the motorhome will steer into it just fine". He was absolutely right. We love mountain driving now and steering is a breeze. Just allow yourself for getting used to it. You'll see a difference. Glad you're enjoying it!
Bluedog: You stated you wouldn't have a car to drive if you got a Class A. In my opinion you'd be very limited if you like to tour the area you're visiting. No, you shouldn't have to drive the 40' to get groceries or drive it around to sitesee. I can't imagine going to campground and just staying there for days until it's time to leave. The fun for us, is getting out there and exploring the area. Plan on towing a car and you'd be a much more happy camper!
