I wonder if Josh Groban was thinking of the GMC Motorhome air suspension system when he was singing this song…..

You raise me up, so I can stand on mountains
You raise me up to walk on stormy seas
I am strong when I am on your shoulders
You raise me up to more than I can be

The air suspension that GMC designed back in the 1970’s was so far ahead of its time, we wondered why more manufacturers haven’t used it.   At the RVX show in Salt Lake City this year it was announced that AKTVS* has brought the system back to life using current technology.

When we purchased our Eleganza 2 the PO let us know  a PPO had modified the Schrader airbag system and valves, in fact there were bag plates in the closet that we assumed  would be used to replace what was currently installed.  From what we can gather the toggle switch they installed in the cab was used to turn the air compressor off  instead of having it run constantly if they had a leak somewhere. Perhaps the leak they had was slow and would hold enough air for the duration of their trip or they kept it in Travel Mode instead of Hold to level it when they were parked.  Either way, it was no longer connected to the airbag system.   Recently we hooked a portable air compressor to test the lines, which did not leak and the airbags filled and decompressed like they are supposed to.   The problem was with the compressor itself and after removing the core it was easy to see it was full of water, either a vent to release condensation was blocked or there was a crack.  We have purchased the Viair 300p Portable compressor that we will modify to replace the current compressor.  both in travel and in camping/hold mode!  Let’s hope for sunny weather this weekend for an ‘easy’ install!
