@kcshoots - Can't seem to find that photo on here. Do you have a link to that?kcshoots has photos of his install somewhere, and I think it strikes a good balance of cost of performance.
I like the ARB dual compressor but two of my friends have had theirs fail catastrophically. You don't have to search the internet very far to find similar reports.
Try reading from post #8 here...@kcshoots - Can't seem to find that photo on here. Do you have a link to that?
What are you desires? Do you just want to air tires/rafts/etc up and down, or do you want to be able to blow out the interior of your van with compressed air, run air tools, etc?So what is the preferred method to on board air? Have seen a few 12v options, nothing really stands out.
You can seat a tubeless with the ARB. Carry a small ratchet strap for those pesky ones, but otherwise no need for a tank for that purpose. Tank would serve you well for blowing out the van or running some light air tools.I'm planning on an ARB twin. I've never read an abundant quantity of reviews indicating poor quality. I'm undecided on the location. I'm tempted to install it in the garage to keep it clean and allow it to be easily wired to the lithium battery (also in garage). Underhood with the Vancompass mount is my second choice.
With the ARB twin, is there a good reason for tank? Seating tubeless tires is the only reason I can think of, but it seems like it flows enough air to accomplish that without a tank.
My experience seating tubeless tires with the ARB dual is that it's not the pressure output, but rather the ability to apply constant pressure. This the reason a tank is not needed. Sometimes it's takes 30-60 seconds. I've had best luck when the wheel, tire, and sealant are prepped and left over night before trying to seat the tire. Also helps to flip and rotate the wheel to spread the sealant while pressurizing.You can seat a tubeless with the ARB.

Ok, I'm sold.If you want lots of air to seat tires or fill your SUP then I recommend the 3/4 HP, 135 psi, 12 volt Puma compressor. Found out about it from the Jeep/Expedition crowd. Popular compressor for big tires. And cost less than half the price of an ARB twin air. May require some mods to fit your vehicle. Not plug n’ play. I have details of my install on my build thread “Baby Shamu”.

If all you want to do us air up and down, then a Viar portable is a cheap and entirely reliable way to go. I run 33's and after dropping them to 18-22psi I can bring the backs up to 55 and the fronts up to 45 in about 15 minutes including getting the compressor out and putting it back. I have a Viair 300P.
Also use it to blow up inflatables for the kids, bike tires, and an air mattress for my sister when her pump died while camping with her in Yellowstone. Got pretty hot pumping the air mattress up but didnt quit.
If you have more aggressive air needs, then the van compass mount is a great way to run a tank, or the ARB Twin mounted somewhere convenient is another great option. I would lean towards the VC mount as I think VIAIR is a better value then the costly ARB. Id rather replace a VIAIR compressor than fork out a second time for the ARB. But I have owned an ARB and it was an exceptional piece of equipment.
I went with a Viair portable also. Any chance you have a link or manufacturer for that power lead? That's a nice set-up.Ditto on what Hamster said.
I have relatively infrequent air needs and the portable unit has always worked for me (in our old Syncro and in in the Sprinter). Airing-up van tires mostly for us, no air tools or anything and I haven't needed to seat a tubeless bike tire while out and about.
You can take it wherever as well.
I also tend to lean towards the less complicated, and Viar portables are pretty inexpensive.
I routed a power lead to the front so I can plug in the compressor without having to open the hood or anything. (I added an in-line 40A breaker to the line after this pic was taken)
