I would certainly agree with Matt. The bag appears to have a very small
internal volume, and that equates to a very high spring rate. Just by looking
at the pictures I would guess it to have a spring more than double and maybe
triple that of the standard spring. I don't see how it could give a
satisfactory ride, let alone provide the height adjust range talked about by
Matt.

This is not a solution for me. I park in more boatyards than campgrounds. In
one of the regular stops, the only place I can leave the coach/office/instrument
shop/tool crib requires that I let the port side all the way down to the stop
and the stbd as high as I dare to keep things from rolling off the table
(dinette) while I am working. If I can't get full travel out of the system, I
can't do that.
It does look clean and it may fill many others need, but doesn't JimK have a
single bag that does as well?

It also is not a convoluted bag -- no cone to roll over and serve to absorb
the shock.

I've mentioned this in other posts, but within reason, spring rate has minimal effect on impact harshness. It will affect roll rate and ride frequency. Unless the unit is actually bottoming out, I wouldn't jump to many conclusions. Frankly, I think increased roll rate will be a good thing and ride frequency is a matter of preference. What affects impact harshness most is geometry, tires, and shock valving. Suspension bushings are also a big factor but we don't have those in the rear.
