thanks for the help tom and FTE

 

Got the compressor in but not hooked up yet
working on the fenders still

 

I run two separate systems. For my airbags I have the airlift 5000 which has a single compressor with a wireless controller for inflating/deflating my airbags. I installed this compressor under the bed above my spare tire. For my onboard air system, I bought the hornblaster nightmare system. This came with dual viair compressors and an 8 gallon tank. I mounted these compressors and the tank in my toolbox in my truck bed. Fits nice in front of my 5th wheel hitch. The horns are mounted in the rear above the spare tire and are on a relay that is activated using upfitter switch #4. The air system has enough power to run air tools.
