Mount both on passenger side outside frame and tube up to my horns that are mounted on my skid plate. You can't ask for a better fit on the skid plate, leaves access for oil filter and everything.
BTW first thing to do is change the fuse holder to a better quality, you can see what happened to mine after a few days.
I can tell you my friend, if you do any "serious" offroading, your system is not going to be happy before long.
My install set-up was
exactly like yours....I made it through 4 Raptor Runs....but then came Havoc in the Hills aka Boulders from Hell.
Tank Regulator got ripped off, tank has huge gash in it and the Compressor took a rock to the head at 50 MPH...it's deader than Abe Lincoln.
My advise to anyone doing this Mod,
Bed Mount or like Joe did his or else, it's only a matter of time.
On a side note, I loved it and miss it. I may get a new one, but will install the tank and compressor in the bed next time.
