New or used, you cant expect to get your money back in 8 months, and with the pandy, 2020 trucks were almost sticker for a bit; unfortunately you purchased at the worst time ever. Right now, new are back to 10k off - I like to buy when they hit 15k+. Try TRED - I sold a BMW on there for 16k when trade in was 10k. I dont know your situation, but I would keep a 6.2 as it will eventually demand more (and its bad ass). Losing 18k is a grand a month for a year and a half - gas or payment or whatever wouldnt make me lose that much. Good luck!
