Thanks guys for you quick responses. The 4 Koni shocks and the Airbag Man rear booster bags were installed by Dale. I agree, he really knows his stuff. And yes, the Koni shocks are adjustable but he has them on the softest setting. And we have already fitted better padding to the front seats. So I think I will investigate the full airbag suspension. That seems to be the only hope.

As usual you members are all too willing to help with advice. So thanks again.
