New to Class A are lots of steering corrections normal?

There are many possible causes for this. Start with making sure your tires are inflated to the proper pressure for the load on them. Have the steering alignment checked. Also check the suspension components. I took the easy way out when I had that problem and just installed a steering stabilizer which in my case was like going from night to day in steering handling. Many Class A motor homes have so much hanging out behind the rear axel that good steering can be difficult to obtain.
