The question then becomes did the manner in which the extension was accomplished create a situation whereby the ride rite system cannot be mounted to the frame without weakening one aspect or another of the frame rail extension?

The installation instructions specify using 2 existing holes on the frame rail. With the frame rail extension done by MorRyde, are those holes still in the correct location for mounting the air bags?

Are you thinking they would move the rear axle back on existing frame rails and then add additional rail length only at back end?

On the Axis I saw the frame was cut and extended in middle of wheelbase, plus there was an extension at rear too. On E-Series frame moving axle back on existing rails is not an option, so maybe that's why it's done that way.

On the F53 by virtue of it having straight rails it may save them some work if they can relocate the leaf spring mounts instead of cutting and welding frame. It's hard to say.

You may be able to look under your motorhome and see how they did it on yours.
