I add my endorsement for the Mountain High system.. My contact has been
with Steve and he helped quite a bit as we tailored a back-up O2 system
for my ES-P.  Another nice feature is free O2 whenever you pass through
Redmond.

Do you mean MountainHigh Oxygen, in Redmond (www.MHOxygen.com)?  It
works great and their service in helping with a custom built-in system
for my ES have been stellar!!!
