The problem that you are having is very common. The issue is that the suspension on motorhomes is adequate at best at handling these larger vehicles. But not to worry because there are some things you can do to make the driving experience much easier and safer.

Your 2018 Thor Axis 25.3 was built on a Ford E-450 V10 van chassis. You can add a steering stabilizer to that rig using # RM47MR. A steering stabilizer will help with that lane wondering problem that you mentioned. It will work to keep the RV in line so you won't have to constantly make steering adjustments to stay in your lane.

Next I recommend upgrading the rear factory anti-sway bar to a much more effective one using # RM-1139-147. This is a true upgrade with a beefier bar and bushings for a much more stable ride. You know that side to side rolling feeling in turns or with wind? This bar is going to combat that and be much more effective than the stock bar.

And finally, you can also upgrade the front anti-sway bar with # RM-1139-176. Basically, everything the rear bar does to improve ride quality the front bar does as well. With the steering stabilizer and both anti-sway bars upgraded that rig will be rock solid! The only thing you'd have to worry about is where to travel next.

I have included some links showing example installations of these parts for you.
