Gadget envy! 😆
This is my humble system:
1. Deflate: (a) JT Brooks deflators, (b) sunblock lotion if afternoon drive 😅
2. Calibrate after deflate and during drive: ARB low air pressure gauge (analog)
3. Inflate: (a) on board twin-piston ARB compressor, (b) 4L ARB tank, (c) Power Tank Inflator (picture attached, works well and is reasonably precise), (d) sunblock lotion if morning drive ☀️
I concur though with @Ahab Shamaa in that the 4L tank does not really speed inflating up, but what to do, it's installed already 🙄
Wish list, but will not acquire because space in SWB patrol is limited, a CO2 tank (Power Tank or Smittybilt) and APEX deflators.
Apart from an occasion when I was shamefully late to a drive, I try to be as early as possible to have sufficient time to deflate the tires and flag-up. Heat is indeed an issue, difficult to get used to, but is okay.
