Many of us are driving bus/truck-based rigs with air brakes and air assistance on other things. Decent-sized reservoir(s) with about 120psi trying hard to get out. The air plumbing, as on my Isuzu, includes front and rear blanking caps, logically the place to “plug-in” air-powered accessories. So, can we attach an industry-approved plug-in pneumatic connector to run, eg, a tyre kit, blow up the rubber duckie, maybe even a rattle-gun? OK, the rubber duckie might be a stretch.
8.6m Isuzu LR, 7.1 litre. 650a/h, 420W solar. Rear-mounted Yamaha outboard (manages 3 knots Lol!). Rubber duckie. Blue Ox towing rig. Suzi 4wd.
