Congrats on your chosen model
Some advice regards air suspension. The area manager of St Johns use to live next door and of course we got quite close to them and as my although I mainly diverted into electrics, my actual trade is in electro-mechanical engineering. Back on topic it came about one day that their mechanic had retired and the new one would always contract air suspension jobs outs, so my neighbour at the time asked me if I could do anything, so I did for what ended up the next 9 years, untill my then neighbour moved to the amulance service as an LAO.
The air suspensin consists of 4 bags (one on each corner), compressor, 4 solenoid valves (one for each corner), control unit, regulator, filter/s for moisture & water.
A puncture of the bag, is the main issue. Road dirt (grit / gravel can cause the bag not to seal in the seat, overtime and can cause the bag to burst – This is less common in the early days.
The compresser, (tyre inflater) has a shity piston and rings in a dry bore (no oil). These can be prone to wearing out due to heat and continued use of inflating the tyre. Solenoilds and control units can fail at any time, but these should be covered under warranty.
The bags should be inspected as part of the service, getting a hose to swill the bags if you are abe too every few months will keep grime off.
