When was the 90k done? At 166k you'll be coming up on another 90k service soon. I'd ask for a grand or two more than book value for your mileage and condition, but being close to a second major service will knock a lot of that back. It also depends on where you list it. People on mud know and appreciate the value of aftermarket items and may be willing to give you a little more for the rig, whereas people browsing sites like autotrader don't give a crap. In the end, its your truck. You have to price it how you see fit and adjust accordingly if you aren't generating enough interest.
