Yeah, I've seen his setup. This is when the jealousy set in! I've wanted them ever since I had my '07 F150. But I don't often spend money when I can't justify it...and I simply don't tow heavy things often enough!
Hello Senix, what is the tongue weight of your fiver? I had the airbags in my F-350 (used Airlift instead of Firestone and they worked great). I got them just to take the little bit of sag out of the truck I noticed when I hitched up my fiver. My tongue weight is right at 2K. I have not hooked up the camper to the 450 I just bought yet, hoping I will not need the airbags for this truck. The back end is a lot "beefier" than the 350 was and I am hoping not a lot (if any) sag will occur when I hitch up.
Looks good, but IMHO mounting the compressor under the truck is asking for troubles.
I have the set, but never hardwired the compressor. I added cigarette plug to it and tire chuck, while the gauges have the air hose with tire valve on it.
It is not likely you need to adjust the airbags during the drive, so having portable compressor I can use it on my trailer wheels and other vehicles as well.
This is high quality compressor. The popular compressors sold in automotive places last for about one inflation of big tire.
BTW the Firestone gauges are not even. When I push both valves at the same time for the inflation, the needles come about 7 psi apart with equal pressure.
