Just wanted to update... I got the compressor and the air tank installed Saturday. I had some leaks that I tracked down today and I think I have corrected them... will watch it over the next few days. If this is all good, I will start looking for an air horn! But, I wanted to give a huge thanks to @Squirrel13 for all the help. I copied his install to a "T" and it is great! I installed the compressor over the spare tire, the air tank in front of the spare tire, and ran a line to the back of the truck next to my license plate for the QD. I will likely end up with airbags eventually... but I gotta stop spending some money for a while! lol.

Do you all think there's a need to extend the air inlet from the compressor somewhere higher up? Or maybe a splash guard in case it decided to turn on to fill a tank while driving in wet muddy conditions etc?

YES

It should be put in a place free of dust and moisture; AKA your truck cab.

There is a vent in the back of your cab between the cab and bed, feed an air tube through there and attach the filter. Then you're drawing air from your cab, ez.

Mine is installed just like the first photos in this thread and my intake is screwed right into the compressor. I did think about running it into the bed of the truck, but I didn’t. I will say that here in the Southeast, I saw a lot of water come out of the drain valve. I think the farther away from the compressor the intake is, the larger the air line needs to be to compensate. I could be wrong here though… but for now it’s under the truck.

I ran my intake about 6' to the cab, absolutely no issue getting up to pressure.

The moisture is from the compressor getting very hot and compressing that very hot air into the not-anywhere-near-as-hot tank, aka condensation. Less to do with the intake itself

The best way to reduce the moisture is to cool that air before it goes into the tank (some ppl install small radiators, I did not). You may also install a water separator on the tank's outlet, which would reduce the amount of oil and moisture going into the air tools.

I plan to install these myself, however, since I have an RDS fuel tank/toolbox on order, I am thinking I would put the compressor in the toolbox so it can be locked up. Then I can run the air hose back to the tank over the spare.

Since I can't bolt the compressor down into the toolbox floor, because that would mean drilling into the tank, I'll make a bracket for it to bolt to which can then be bolted into the toolbox front and rear. This will also provide additional air cooling between the compressor and the fuel tank.

Does this sound like a good or bad idea to anyone?

Not a bad idea. Honestly, I'm toyed around with the idea of even mounting the tank inside my toolbox. Since I hava the 7.3 gas it gives me plenty of space in the engine bay I can fit the compressor there, so routing a hose to the toolbox where tank will be easy. This way I can install the quick air disconnect on the toolbox and plug in hoses as needed. I dont plan to use it for air bags.

I had my compressors and tank installed in the tool box. The air connection is located by my hitch. Works great, runs my on board air and my train horns.

I m just worried that since my toolbox sits on top of the fuel tank and the compressor can get warm, there might be issues.

I've had no issues. Mine has been installed for over a year.

While installing a 5th wheel prep package this past weekend on my '22 F-350 Lariat, I also added Load Lifter 5000 bags and the on-board air compressor. For the on-board air project, I very closely followed(copied) Squirrel13's installation and it turned out great. I ran #6 wire directly from the battery with a 40amp Maxi fuse in-line.

I was able to pull the #6 wire along with 4 additional wires[(1)12ga. and (3) 16ga.] inside the frame all the way to the back near the spare tire. One of the 16ga was run from upfitter#1 to the small gauge red wire connected to the pressure switch. The additional 3 wires are for future use. Since my 5th wheel tires require 110psi, I replaced the stock pressure switch (70/90) to one with 90/115 specs.

So far I have been very happy with the setup.

Finally got around to doing mine!!! Works awesome.
. I left a little bit of the 6 gauge wire toward end wrapped around that crossmember because I may route it to a waterproof fuse box and have a blue seas systems 12v USB and Cigarrette plug in bed of truck.

I'm going through this install now. Where did you get the coupler to convert from the 1/4 inch air hose to the quick-connect adapter that you installed on your bumper? It looks like you have some kind of threaded adapter, but I can seem to find anything like that.

Thank you!

Jeff
