These are an option to the x-chock.
Fastway-onestep wheel chock by Equal-i-zer (the hitch company).
I got mine through RV Wholesalers but the manufacturer is Progress MFG in Utah.
It is mandatory to get the XL version for the spread axle.
I paid $54.99 each (2) then had to call the manufacturer to get the extension to make it the XL version.
100% of the motion is GONE, thank God!
I know these are not cheap but they work great, solid as a rock.
