Recently I bought Viair 32 Air Down Gauge to make airing down for trail runs easier. I paired with the Viair 88P Air Compressor to air back up after the run.The Air Down Gauge works quickly and easily. It can be used as a normal tire gauge as well. Screw it on, then it's easy-peasy hands-free deflation. On my most recent trip, the deflator aired down each tire to 20 psi with the quickness.
After a trail run, the 88P Air Compressor comes in handy getting all of the tires aired up within minutes. The air compressor is going to be a temporary solution until air lockers require getting on board air gets put in the 4Runner (hopefully in 2017).The 88P attaches directly to the battery, which makes for more power and quicker inflation of tires. This unit beat all of my friend's units (a Superflow unit similar to the 88p and cigarette charger compressors).
Five-stars for each new toy. Ready to use them again, soon!
