Demountable camper group

Needing to maintain a minimal amount of air in system (as recommended by manufacturers) been looking around at ways to make system do this by itself when not carrying a camper.

Not really anything on market to add into system and detect low pressure and add some automatically, experimented with something used in hydroponics (irrigation)
where when a fluid passing through a valve suddenly stops the component can be made to trigger a valve or tap
but these operate at much much lower pressures than I need, and consequently worked initially, but failed.

I have a gauge to monitor air pressure though but at night can't read it well, so instead of all the wonderful things in my head I had to fix it



...........installed a short LED lamp alongside to illuminate it instead.


I know many of you will feel short-changed and may be exhibiting signs of disappointment at this pedestrian solution,
but it was raining and I'd already branded myself once this morning with the soldering iron

I'd have just gone for a head torch


Seriously though, there are tyre pressure remote monitoring things about these days, i'm too lazy to google them but would they be able to be set at say 10psi?


TBH I just bung a bit in - guesstimating 10psi and check every now and then with a tyre pressure gauge.

Maximum: doesn't matter,
Minimum: a bit more so.

You remember mines a reservoir of air held in a tank underneath, its on tap so just needs something to trigger the fill valve occasionally.
Cold weather causes an ongoing loss of air so fitting a regulator (like in scuba) means overnight it would have a good go at emptying the tank, and then compressor works overtime to build it up again,
so thats out!


tank BTW also allows me to carry a curly hose & gauge to deflate and fill tyres at will
