Nice.. I have mine mounted in the back on the right hand side. Basically where the subwoofer is in the limited and above. Just need to build a cover for it and it will be completely hidden.
I like the look of that compressor. I'm still using an autobahn special, it is slow going. I'd love to setup a compressor with a tank. I remember someone installed one under the spare wheel well, that looked good.
Believe it or not, this little ARB compressor has a tank, It's that horizontal grey cylinder thing in front of the blue motor. It's only small but it does the job. When switched on, the compressor runs for a few seconds until the pressure cutout switch on the cylinder cuts out. When the nozzle is attached to the tyre valve releasing pressure, it cuts in again. My TJM stand alone el cheapo is rated at 72L/m max. This would be at no load. It falls away rapidly above about 30psi. The tiny ARB CKMP12 is rated at not much more at 87.2L/m no load but 66L/m at 29psi. I think that is what makes the difference. My daughter's temp spare was at 40psi and had to go to 60psi. The ARB was so quick I thought I was going to blow the tyre up. The compressor motor wasn't even warm.
