After being ridiculed for always being that guy who is the last person to finish airing up (slow Viair 90P cheap compressor), I decided it was time to look into installing a better on-board air system.
After doing a ton of research on the various compressor options out there, I decided the Viair 400P was the best option. The 450P is 100% duty cycle, but puts out less CFM than the cheaper 400P. The 400P is only 40% duty cycle.
However, more research lead me to the 400P-RV. The RV version of the 400P had additional accessories but more importantly it has a built in pressure regulator that automatically turns off the compressor when you move between tires. This allows the compressor a short time to cool down.
Amazon has the best deal I could find for these.
The process of fabricating up a mount for the compressor was pretty easy.
1. Take the metal base off the compressor and remove the rubber sides
2. Use the metal base for a heat shield to prevent the compressor from melting any of the wires. I zip tied this to the frame.
3. I used some angle aluminum as rails for the base. I bolted the compressor onto the rails
4. I bent some metal across the aluminum rails and up and over to attach on the front metal support rail running along the top of the grill.
5. I used rubber washers between the compressor and the rails to help prevent vibration. I'm not sure how much good this does, but it really can't hurt.
6. I used the existing nutsert to bolt the top of the bracket into. I just found a bolt in my toolbox that just happened to screw in there perfectly.
7. I cut off the big alligator clips and wired the compressor into my aux battery. I am currently still using the switch that is on the end of the compressor. It seems easy to access (this is the reason why I mounted it the way it is).
I have not had a chance to use this yet in the field, but hopefully it doesn't get too hot. If it does, I plan on extending the filter out a little with a hose.
