Hello, would you call me about the trailair. I can get photos of it sitting uninstalled if anyone wants to see it in present condition, but it really doesn't look much different than above minus a little bit of weathering from trip use. We haven't planned any outbound trips yet, but as we do, I'll certainly keep up here with updates so we if happen to be in your area, we can bring it with us. I can meet someone within a reasonable distance on a weekend, I'm near Lawrenceville, GA, and I'd consider driving out around 100 miles if the offer is good and I can bring 1 helper to assist with wrangling it, but you'll need to be the other half of the help to physically move it.

I've seen estimates of it weighing in at 184lb, but my guess is more like 200-230lb, maybe more as others I've seen rated between 230-250lb. I'm looking for any reasonable offer, that does not require me to ship it, It weighs a lot, and I can not move it due to back injuries. It has never seen long-term exposure to the elements otherwise.

It is now sitting in our basement protected from the elements. I estimate the kingpin to have about 8k miles miles on it. The trailer is stored at a semi-enclosed storage facility starting about 2 months after this installation photo was taken at our previous storage facility which was also at least covered. It was installed on our 2016 Heartland Road Warrior 420 on Jas show here: This is the link to where I purchased it from originally on Apfor reference: Prior with our 20 in combination with a B&W Campanion hitch, this air ride kingpin eliminated pretty much all chucking and suspension jounce that our Ram would produce making the ride much less fatiguing. We uninstalled it on Februbecause we have switched to a Sportchassis MDT for a tow vehicle and now use a Trailersaver hitch. I have for sale a Trailair Air Ride 5th Wheel Pin Box - Lippert 1621 with a 21,000lb tow rating, model number LC158778.
