M154's are pretty aggressive for a motorhome. They have more tread squirm than highway-tread tires, and when you install the on the rear only, you often get a little over-stear sensation, but its only from the tread squirm. It will get better as the tires wear.
You can also fix this by installing the same tires up front, because then they will also require more "slip-angle" to change direction, so they balance out.
PS - I run M55's, which are the same tread pattern but in light-truck flavor. I also ran M154s on several medium duty trucks.
Never had any tread squirm from M-154 Toyo tires. They are a very good tire.
