Hi folks.

What's the maximum working pressure of the rear airbags? We are on a two month trip up into Quebec, Nova Scotia and New England and I'd like to leave some safety margin on these bumpy roads...

Thanks folks - oh and direct email to Richard.Lister at Yahoo.com would be appreciated as getting online can be tricky.

Cheers

Reportedly, 150 psi.

My coach is undoubtedly lighter than yours, but I reach full height of the suspension around 100 psi. I have pumped bags up to 120-125 psi on any number of occasions, and driven over some profoundly bumpy roads. But there is no need to pump them up higher than the maximum suspension height--any more and you just put more stress on the extension of the shock absorber.
