See what RMR 4x4 in might give you for it. They look to be buying these up from all around the country and have a client base that seems to value a truck with modifications like this. We bought a Land Rover LR4 from them years ago and they are great guys.

When I looking at buying this system I always found photos and videos to be helpful so figured I'd share a short video of mine as we got ready for a fishing trip to the Outer Banks in case it helps anyone.
I used this:

Glad I could help! Hope you had a good rest of the trip!
My truck was filled with sand over the weekend on Cape Hatteras so I'll probably be doing this again soon!
Yeah that's exactly what I've been looking at. I like how my truck rides now so was trying to avoid heavier springs and just use the airbags when towing or if I'm really heavily loaded. Might be worth trying some tapered springs though.
