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.
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've been using the ARB portable CKMP12 (looks like a tackle box) for many years, no problems filling up 33's. Plus, since the entire setup is easily portable, I can take it wherever whenever.

For a fixed mount setup, Agile also offers a complete solution; https://agileoffroad.com/product/agi...-air-sprinter/

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.

Default On board air?

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”.

Ok, I'm sold.

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)

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.
