Arb twin air compressor under bed mount

Looking for any info or experience with mounting an arb twin air compressor underneath the bed of my Tacoma How resistant to the elements are they? I don’t do any serious off-roading just mountain roads looking for camp going through mud puddles and dealing with road grim/spray or dust etc. Do you think there’d be any issues with mounting the compressor under the bed could exhaust heat be an issue as well it would most liking be mounted to a compressor mount that would bolt to the bed

 

The reason most folk put them in the engine compartment is water, and ease of wiring. These are air pumps, not water pumps, lol.

Having it exposed even under the bed, will accelerate wear and tear from the elements. Dust for sure, and even water, while not necessarily getting submerged, you are effectively spraying it directly with a hose when you drive in the rain.

If you really want to put it under the bed, I would definitely build a box for it to protect it as much as you can from the elements. The box can't be water/air tight (obviously). The other issue is wiring. The farther from the battery you put it, the large the gauge you need, and also just the effort of physically routing the wires (vs. just a few feet to the battery inside the engine bay).

The exhaust heat shouldn't be much of an issue unless you're mounting it WAY too close, lol. The pumps do tend to get hot with extended use, but they have thermal protections to prevent damage. If the exhaust gets it too hot, it'll just shut off more often.

I would consider building something in one of those slim contractor boxes for the bed.

 

@jbrandt thanks for the input that’s what I was worrying about the only reason I thought of mounting under the bed is cause I was thinking of getting the arb twin air compressor and it won’t fit under the hood of my 1st gen I can fit the arb single which for me the single will probably be enough primarily just for inflating 33’s

 

I have a Viair 400P, and it does a fine job for tires. I also have a portable tank (one of those harbor freight 5 gallon jobs), and I can inflate it too, for if I need faster air (like seating a bead or something).

If you're just inflating tires, you don't really need the twin. That's really more for air tools or simply inflating tires faster.

I think you'll be happy with the single.

 

I just killed my

$177 Smittybilt 2781 Smittybilt 5.65 CFM Air Compressor - 2781

Smittybilt 2781 compressor after a few days flying through Baja trails. It’s located under my bed lol.
I didn’t make a cover for it do to time constraints and it must have sucked up too much dust. It’ll kick on and die. Going to try and fix it and finally make a cover/shield.

 

@frenchee bummer I followed along with your stories on the gram it looked like an epic trip I love the super pacific camper I’m wanting to eventually go that route with my Tacoma any concerns or dislikes about the camper after taking it to Baja would love to see some pics of it on Instagram

 

I have the twins also.
I suggest installing it within the original ARB harness length. You can shorten the harness BUT not lengthen it. I did this and melted a section due to the amount of amps they pull, 56 IIRC.

Keeping it under the hood keeps it clean too.

 

No ABS module?
I think I have an ABS module there.

 

I'm terrible making actual instagram posts. I think tonight I will try to make a few posts of the truck starting from a few months ago, to recently.
If you PM me your number I can send you a few shots through text or whatsapp. I had no issues with the camper and absolutely love it. I do have a couple recommendations though.

 

Get rid of your ABS altogether. I did and man, what a difference.
I removed all of that crap when I did the SAC and rear Diamond axle install.
You will need to add a Wilwood PV which is tunable and works great.

 

Dont wanna pollute OP thread but I almost did during my 4x4 swap.
I actually had non ABS spindles (no holes for sensor) and transferred the hubs to my ABS spindles.
Big regret, I've always hated the ABS. Its much safer in snow and rain without it right?
Whenever I barely hit the brakes in snow or rain the whole thing just goes crazy. I've found doing my own modulation is better lol.

 

@johntoyota 's ARB didn't like the elements too much

 

Have not read this post, but I had mine in a box on the left with a bottom door and no top door and no fender liners. The relays didn’t last long.

 

Jbrandt's recommendation is a very good one. I have been using viair compressors for my air ride suspension on my street trucks and they hold up very well. I recommend mounting the relays high and dry but you can purchase Viair Dual Packs (2 Compressors) and use a slim 5 gallon tank and you will have air for days.
