TrailAir Pinbox Observation
TrailAir owners:Just before a 2300 mile trip this fall I installed a TrailAir pinbox on my Open Range. I settled on 55-60 psi for the bladder and enjoyed watching the trailer float behind me. I notice...

Beware that the "arrow" indicator sticker on the shock is evidently added by the installer/improperly by the mfg sometimes incorrectly. When they installed my TrailAir someone misapplied the arrow and it was to high and required to fill the bladder completely to reach the arrow tip. Consequently I marked the shock with no air.-- then half way and finally when the bladder was full ( fully extended shock). I found the trailer travels the best when between 1/2 AND 3/4 extened at the shock. At the point there is minimal chucking and better ride..... Mine rides with 70-80 PSI with a pin weight of 3100lbs.
Yes, I inflate mine to the high side of mid stroke and have marked mine with colored tape.
When I received my pinbox I saw right away that there was no yellow sticker on the shock absorber and looking closer I could see the arrow was stamped (engraved) into the shock and of course painted black...impossible to see. I called Lippert and asked them for a sticker with the arrow and was told that the sticker wasn't available separately and they would send me the whole shock absorber. Well, I got the new shock 2 days later and guess what? No sticker either!
