An experiment that turned out to be way more involved than I had initially anticipated. I had the bright idea that since the Firestone RideRite airbags have a very limited internal volume, and so therefor the pressure will vary widely while driving, creating a pogo-ing effect, what if I added snubber / accumulator tanks to the circuits and added at the same time, an option to run the circuits in parallel, or tied together as a pool. So I built the system using Firestone 0.5 gallon pressure vessels and then found out my measuring skills didn't come out to the task and I had to change the plans on where the whole assembly was going to reside. So I mounted it vertically on the passenger's side; between my big steel toolbox and the rear cab wall, and then found out the complex ballet of pipe fittings I constructed to tie everything together, wasn't airtite even after going back and retightening everything once. So I stripped it down to minimum and installed pipe plugs temporarily where the cross-over manifold used to be, until the weather improves and I can have another go at it. Just proves the theory / concept of the age-old "mice n men" thing.
