Toyo tires are very good tires. That is what I installed on my coach when I replaced the XRV Michelins. I got the 265 75 on the 22.5 I also had them balance with Equal and had the special screened filtered schrader valves installed to prevent any leakage. If you don't install the X air valve stems, you will have leakage problems because the powder will get under the valve seat. But with those special valve stems, Equal gives you a very smooth ride.
Sounds like you will have her on the road pretty soon. Good luck and have fun.
