I paid $4300 for mine, full load, new (300 miles)performance diesel tranny (E4OD), mint body and very good interior, rhino lined box with fully lined camper shell centerline forged wheels, big stereo with new amp, subs etc. It was what I wanted an most important to me, original owner who babied it. I knew I was buying a good truck. Your $1800 sounds fair if it needs work.
