Good luck with the sale. Price seems about right given how rare these trucks are and the current demands for off road trucks. Plus this rig is fitted with a V8, Rancho lift, moon roof, leather interior, Hardtop cover, Apple Carplay/Andriod radio, and roof rack, all which I think add value to this truck for almost all buyers.
The other upgrades I like are the snorkel, trailer brake, and blacked out look, however this is where I think Happy Hummer has a point and it takes the right buyer willing to pay for these to already be installed since quality of parts could be lacking or installed incorrectly/unsafe.
