I have an ARB dual in my huge Ram5500 Camper with 42” tires, and had one hard mounted in my Tundra.
Both have worked flawlessy for years.
However, i am a "red tool addict" and got the Milwaukee M18 cordless one as a backup for my camper since its on bags, and a compressor failure would make for a bad day.
The Milwaukee works so damn good, its become my primary and never leaves the camper. In fact, i just bought a second one for the 200 and will not bother installing a hard mount compressor.
Its MUCH quieter, slightly faster, and doesnt require any hoses or fittings to fish out of the truck.
One HUGE advantage i like on the M18 over the ARB is the digital screen and PSI set, set it to 80psi (my rear bags) turn it on, and it auto shuts off when it reaches it. Set it to 95 (front bags) turn it on, shuts off when reaches it.
Its a ton easier and overall i prefer the M18 compressor if only had to choose one.
The ARB dual works, and definitely does the job but the mobility of a small but just as, if not more powerful option is the better choice, IMHO.
In the past, i have run them ALL, belt driven York (still the undisputed king of OBA), Oasis, Extreme Outback, ARB, etc....
I would rate the belt Driven York hands down the best, and then the Milwaukee cordless.
I also love the mobility of the M18 and have used it on various other projects without running hoses
This is the model i am talking about:
The Milwaukee Fastest 18V cordless tire inflator. The M18 inflator delivers fast, accurate, easy inflation with the portability to take anywhere. Optimized for passenger, light truck, and other medium-duty tires. Rated to deliver max 150PSI, the high efficiency motor tops-off 33 in. light truck...
