In the ammo can... seems like heat may be an issue?
I've had the Extremeaire Magnum for a couple years now. I got it as the portable unit but have since fabricated some mounting brackets for both my Taco and my 4Runner to place it under the hood. It's pretty large compared to many others and is also pretty heavy, 35 pounds if I remember correctly. The unit is totally sealed against water or dust penetration and can be mounted in any configuration, sideways, upside down, etc. The air filter can be detached and mounted remotely by simply running some tubing to wherever it fits best and will get clean air. The manufacturer says many Aussies mount them "down under" on the frame rails. 100% duty cycle and will run an air gun without a tank with no problem. I'm usually out on the trails alone but on a few occasions when I was out with a group, I'd air up my tires and usually at least 2 on the next vehicle.I used a Viair (Branded as Bushranger overseas, but I think they are the same product) for several years in Dubai. IT was a reliable as an anvil. I later "upgraded" to an ARB twin because I was jealous of the one in my wife's Jeep. The ARB was a lot faster, and almost as reliable. (problems in the desert with filters and current draw, but it never stopped.) Both will serve you well, but get the best you can afford. Nobody ever complained that their compressor was too fast. I would happily buy the ARB twin again.
I am tempted by the Extremeair Magnum, but I have never met anybody who owns one.
ArmyRN I actually like the setup! I ride 2 different vehicles and looking for a setup I can carry in either... as a backup. I use CO2 but on one longer trip I ran out and had to find a refill. Had buds with me if I had need air but looking for compact backup. Can I get specs?
