Also, how are the front tires? Are the properly inflated, per the actual four corner weight of the coach and tire manufacturer psi charts, and not too old, and not showing signs of uneven wear. Tires, can add to wandering, if not properly dialed in.
Best of luck to you, hope it's a simple adjustment,
