MURPHY55347? Do you tow a car? And if so, do you notice any difference when towing and not towing? We notice much less "wander" when towing. It seems like our toad acts like a stabilizing anchor. Not that it would be a practical solution but I'm curious if other people have noticed the same thing.
And, on a previous rig with severe "wander" problems, after trying several remedies, a front steering stabilizer turned out to be the answer. At that time, more brands were available than just the Safe-T-plus at a much cheaper price. Safe-T-plus seems to be the only one sold currently, and they do a great job according to people who have installed them, but they're a little pricey.
