I had local 4x4 shop install the system and they were awesome! The mechanic took the time to go over everything with me before he started and then sent me pics to confirm placement of the quick connect fitting and again walked me through the install when I went to pick it up today. The install for parts and labor came to $1000. I feel I got a great deal, especially since I can tell the install mechanic really takes pride in his work!

Another $100 bucks at Advanced Auto Parts got me a built in digital pressure gauge, 50 foot coil hose, fittings and blow gun.

They confirmed I would'nt ever be installing power running boards before install (sorry wifey, you gots to climb!).

Air fitting tucked out of the way, and bleeds air when hose is disconnected.

Nicely done!

Wow, looks great! It looks like it's installed on the passenger side of the truck? The lable on the compressor says dual. Are there two compressors? When I look that model number up on their website it shows a picture of two compressors. I guess I need to read more about it. Would it be possible to get more pictures of exactly how it's attached to the frame? Can you supply a parts list of what components were used, like tank man and model number? Thanks. And again it looks fantastic!
 
Two problems I see, first off that filter/water separator between the tank and regulator looks like its placed to low. I can see that getting damaged. Also your choice of air hoses, never had any luck with those, always getting kinked. Otherwise looks nice.

Yes, its on the passenger side. Looks like a single piston compressor to me, I dunno why it says dual. I called the installer at MTE Accessories and he is gonna text me over a parts list tomorrow so I can post it here.

Two valid points. The bottom of the water seperator actually sits pretty high up though compared to the fuel tank skid plate and drive shaft etc. The glass bowl can easily be unscrewed and removed if rock crawling.

When you find a good compressor hose that isn't on a reel let me know. They all suck. Atleast with this one, I dont have to roll it up and it fits under the seat easily. It doesn't seem to be prone to kinking easily like some others I have used but it can be a pain in the ass to untangle.
 

Kind of looks like this kit I was considering. Might be an upgraded 5 gallon tank instead of the 2.5 gallon.

I like the idea of having the air valve in the bed of the truck to keep it clean. I had originally seen it coming out the bumper or underneath the truck. Only downside is another hole in the truck bed I guess.

My aluminum tank is 3 gallon. I was concerned about the air fitting getting hit by something being loaded in the bed, but that location works pretty well tucked out of the way.
 
Where is the water drain for the tank?

Good question. There is a plug on the bracket side, like it should have been mounted bracket facing down. I'll have to address this with installer.

Gonna pull an Iron Man and answer myself LOL

I called the installer, and he said he doesn't think a drain is necessary since the tank is aluminum and the water seperator should catch it from pressure leaving the tank. I disagree, and found a great aluminum welder to weld an aluminum (1/4") half coupling on the tank on a lift, so I don't have to remove it.

@GaryDE thanks for bringing this to my attention!
 
This will likely be my first mod. Some of the beaches here in CA allow on beach use for offroad vehicles and I want to be able to air down and back up quickly and conveniently.

What's something like this cost?
