I decided to get a better on-board air compressor. The one the original owner installed wasn't a constant duty air compressor like you would want when filling 37 inch tires. The original compressor could only run for 20 minutes before needing to be cooled off for 20 minutes. I already own a Viair constant duty portable compressor so I decided to upgrade the compressor on this rig to a Viair 450C constant duty compressor as well. This compressor is nice upgrade not only for the constant duty if offers but it will turn off when the system reaches 150 psi. The old compressor would just run and run until you turned it off maybe because it was really tired and could never achieve the 150 psi rating it had.
I know with the location under the rig being exposed to the elements isn't ideal but a quick check of the side compartments in the cargo let me know the compressor wouldn't fit in there without some type of modification. So, under the rig it went. The original mounting plate wasn't going to work so I had a fabricator local to me help me make a new plate for the installation.
I wasn't sure which way I wanted to go with an air hose to use, but for now I'm using a heavy duty rubber line from Home Depot. It's way longer than I need, 50', but I thought this length might be nice to have if you had a person in your wheeling group that needed some air and the extra long hose would reach all 4 tires on their rig as well without having to reposition it. That hose is pretty bulky but it does fit in my passenger side cargo compartment. I think ultimately I'll convert the supply hose to one or two accordion style hoses like Viair supplies with their portable compressors.
I'm not too familiar with these push to connection air lines but the straight fitting on the one shown in this picture is leaking. It seems they are used for lots of application so I guess they are legit. I ordered some new fittings and tubing so I can hopefully get this system leak free.
