Dual Pump Compressor Bed Mount (NAPA, THOR, MORRFlate, Maxi Trac etc.)

[howeitsdone]

I bought one of the NAPA dual pump compressors which is the same as MAXI, THOR, MORRFLATE, etc... and I wanted it in the bed rather than under a seat. So after thinking a while I decided to see if I could flip it 90º and after a little cutting into the mounts it worked perfectly. So it was just a matter of welding on the back nut because you lose access and then mounting into the side of the bed. (slightly crooked, whoops...) Will use loctite since the nylock is melted.

I kept all the original bushings in the same places. I also gutted the internals to prep for the mods and flipped the heads so the button and quick connect is facing outward. I'll put a 90º for the type d coupler so that I don't have to make space when I want to use it.

Next on the list is the compressor mods for pressure switch, type d, PCB board elimination, 4-tire system, and running some 6awg from the battery to the back. All the supplies arrive on Tues/Wed this coming week. I'd ultimately like a busbar on the inner panel and then use that plate where the 120v would be to add some 12v ports.

Edit: As chorky mentioned a post below you should sheathe the cable. This is not a DIY on the electrical side. There are plenty of those floating around. This is simply to show a way to mount the compressor in the bed.

Very impressed with that approach! I've been holding out on the decision to place under seat; just wasn't comfortable with the expense and location. Would rather use that space for something more secure, like for gun storage (under seat or behind rear passenger). Pls continue to share the details of your progress, I'll likely use the same approach.

Made some progress with the compressor mod this evening before the sun went down and forced me to stop. Still need to wire in both switches, but after that it's ready to go. Then I can move on to the easy task of running the wires from the battery to the bed and be done.

And the final product is, well... it looks the same as the original photo lol.

Wired 6awg from the battery, down to the frame, and ran along the wires on top of the passenger frame rail all the way to the back. Left a little extra for when I figure out how I want to do a buss bar system back there. I'll also need to add another set of Andersons so that the bed can come off if needed.

Added a breaker in the front as well which is super handy because I can disconnect if I have the cover off the bed so that someone doesn't just come by and turn it on. I didn't see the need to route a button in the cab when I'll be at the compressor anyway.

Was able to use the 4-tire air setup and worked great! Very happy with the result.

Ignore the debris on the battery cover. A bird started making a nest in there last night...

You really need to be putting that cable in some protective sheathing of some type. Either the old school cheap plastic stuff or the newer Chinese finger trap type stuff. Having only the wire casing itself is asking for trouble. Especially where it goes through the bed in the hole behind the tie down bracket. Bad news right there. And having a 6ga cable shorting is really a bad day. Also make sure you have a fuse where it attaches to the battery appropriate for the load.

Also a quick note that you don't have to weld those mounting nuts like I did. I realized after I mounted it that I can just remove the bolts that attaches the mount to the compressor on the sides. It's a Metric 4.0 Hex.

Good advise for someone else looking to do this. I've already addressed those concerns outside of these photos.

Yeah, too much work for me lol. I just bolted mine to the bed. It’s been over a year now, no issues whatsoever ??

I'm a sucker for making things difficult lol. Your image in some other thread was the inspiration since you showed it could be put there. I just had to have my generator fit in that same place so mounting on the bed wall was the only answer.

Nice! Glad I could be of assistance lol. I’m actually considering a complete Molle setup for the bed so I can get it off the ground and add some fuel tanks and traction boards back there. Realistically, I’ll probably just leave it there and work around it lol.
Oddly enough I JUST put the pressure switch in my amazon cart yesterday. Gotta get that done soon it’s a good mod.

Place that order! Had to have been the easiest part of the whole process IMO. Plus integrating into the original power switch was a breeze.

Have you had any issues with rain or snow with the compressor being out in the open?

I have a tonneau cover on at all times so I don’t have any issues. If I wash out my bed I just unplug it and let it dry out if I get any water on it.

Makes sense. I don't have a tonneau cover so I may have to figure something else out. I can't imagine it would last with getting rained and snowed on all winter. Maybe some kind of waterproof cover would work.

I would look into a winch cover in that case. You can probably find something similar in size.
