AIR SUSPENSION CONTROL PANEL

Has anyone had rear axle supplementary air suspension fitted to a pre-2019 model year Mercedes Winchcombe?  If so, any recommendations about where best to ask the installer to fit/locate the control panel?  Ideally would be dash mounted but not sure if this is possible?  May also have HPC hydraulic levellers fitted at the same time and wondered if anyone with a MB coachbuilt has them and where the pump/oil tank and also the touchscreen controls were fitted?

No experience on the Mercs but the Ford, Fiat, Puegeot and VWs have the inflation point mounted in the cab door footwells

On our Merc Bourton the Gauge and valve is fitted just inside the Hab door on the fridge wall, don't know if this is classed as control panel. Thats where it was fitted when we bought the MH.

Not Merc, but Ford, I made & fitted an enclosure to hide an on-board compressor & tank, & the control-valves etc mounted on the front panel, it took a bit of the under-sink cupboard, but there is way too much storage in the van anyway! I got the air/dump valves from the states, just a 'paddle' valve, 'up' for up & 'down' for down.

Thanks for all your replies and suggestions - very grateful.
