A 22.5 is going to look narrow. But the Mitchlin XRV 22.5 fits very nicely atop a 12 inch wide plank (As in 2x12)
Since my hydraulics are not all that good I have a set of 2x12 stairs.
Two feet long
And a full yard long.
Glued together, Drive on or back on as high as you need till the bubbles center.
Home is where I park it!
