Once you have the alignment figured out, or whatever is causing your Monty to not track straight and true, I'd suggest adding a steering stabilizer. Do it AFTER the pulling issue is corrected, otherwise adding a steering stabilizer could mask what's really causing it. I added one to my swb Monty, and it helps keep it on track pretty well. The swb ones can tend to wander and jump around, especially on bumpy or irregular pavement. But with the steering stabilizer and larger tires (265/70-16), it actually rides quite nice and stable.
