It was a lot of work, but take off the mods you can sell and either trade in the JK or private sell. For me, the dealer gave me a good value on my trade in Sahara JKU if I left the lift on. The rest of the mods came off. Like many, I’m waiting for my 2019 JLU. So taking off the old mods gave me something to do in the meantime. Good luck to you!
