Until the big gust last weekend, I have been pretty successful at keeping the RV between the center and edge lines.

Your motorhome is probably not sliding as if the tires lose traction. My guess is that it's a combination of tire slip angle plus steering being affected by the side forces which roll the body on the axles.
Solid axles front and back with leaf springs as used on F53 chassis is also relatively crude by automotive standard. These are not going to handle like a car.
Also, if the wind is strong enough it will blow just about any vehicle off the road. A strong gust once blew me off into shoulder while driving a relatively stable minivan. I'm not sure what it would have done to an RV, but expect it would have been far worse.
