    To be honest, what follows is not really a "cost effective" idea but a concept I've been kicking around for some time and it turned out a little more intensive than I imagined, but like a lot of things, once started down the rabbit hole I was committed to finishing it.

    I already had a 10awg power wire in (place wrapped up under the rr fender well cover tray) but it turned out to be too light for the load so I replaced it with a 8awg wired fused near the battery - that worked well but if I had to do it over again I would likely use a 6awg wire.

    For the mounting I sourced materials I had on-hand. The compressor (Smittybilt 2781) sits on a 3/16ths horizontal steel plate which is horribly welded (by me) to a steel cover off of a sub-panel breaker box which is attached to the 3/4' plywood side of my cargo box. The horizontal portion of the mounting plate rests atop some very dense rubber pads that are attached to the little storage tray above the rr wheel well - I may have to beef that up just a little as it looks like it's leaning just a tad to the right.

    I replaced the funky non-standard air fittings that comes with the Smittybilt to what is standard for us in the US. The storage tank is a 2.5 gallon VIAIR. Power to the compressor is controlled by a master switch at the front of the box which then is fed through a 90-120 psi sensor then onto the compressor. The system has two manual air valves - one at the tank inlet and one for the tank drain.

    THIS IS NOT A COST EFFECTIVE INSTALL! I have $80+ just in all the brass fittings, then $80 for the tank and a buck eighty for the compressor. I just didn't want the compressor under the hood and exposed to all the elements. Where its currently mounted is a space that was going to waste anyway.

    This should've been a one day project (20 years ago) for me but I spent about a week on it (between naps) at 77 and I swear I wouldn't do it again - I'd hire a hungry young person to do it while I supervised from a lawn chair. :rasta:

    That's a clever and clean way to install it- looks like being 77 has it's perks, gaining the wisdom needed to come up with a better solution than 27 year old you likely would've had the patience to pull off.
    Kudos old-timer, and thanks for sharing with us!

    Way, way cool Dad! I'm so envious of your talent to create things from scratch, from just an idea! Especially with wiring, I wish I understood it all better. Love what you have been doing with the runner, you make me proud!

    Here's how I mounted my Viair-88P.

    Quick and easy. :)

    That is definitely quick, easy, economical, and more practical than mine - but doesn't take into account an old man's folly.....

    I like that Jerry. I don’t have any projects in the planning stage that would require that but think I’ll order one “for stock” just in case the need arises. I enjoy electrical projects as long as they don’t require me to be on my back looking at the underbelly of a dashboard..

    Same here... I was just thinking that when you are bored :) you would want to clean up the connections at the battery. My old truck had something like six at the solenoid (Ford) when I got it so I had to do something.

    I moved out of Northern California (the Sierras), it's beautiful there - nothing at all like the asphalt jungle of Southern California but circumstances at the time caused me to move to Florida but I shoulda picked mountains somewhere - anywhere...:annoyed:

    I’ve seen those before on Amazon while searching out other electrical stuff - thats actually a manually resettable circuit breaker which would be a nice circuit protection device placed as close to your power source as possible.

    Exactly, I velcroed mine on the 300Amp lithium battery, as an extra safety measure, on the top of what is fused in the trailer. And agree, every fuse should be placed as closed as possible to the power source to avoid "unprotected" shorts.
