I have the exact truck, except in white and a little bit more miles. Mine was originally listed for almost $17K, but was able to bargain down somewhat since it was on their lot for a while.
Couple things to look for, number one is the frame for rust. There's only about a year left on that truck for the recall. The leaf springs have a recall on them to be replaced due to corrosion and cracking. They'll replace them for free. Front drivers needle bearing (front differential) goes bad on almost all of them, lifted or not. Between 25-45mph you'll feel a vibration and slight groaning noise. At those speeds, driving strait turn on the 4wd. If the vibration/noise goes away you need a new bearing or an aftermarket sleeve. Steering shaft joint by the rack is prone to rust and getting super stiff. Carrier bearings and u-joints are common problems as well.
My truck has/had every one of these problems. My frame was found to be ok and was coated by Toyota. The needle bearing in my truck was replaced with the aftermarket bushing due to my 2" leveling/lift kit. Expect a $500 repair on that issue. The steering shaft issue on mine is temporarily relived as I sprayed the joint down with PB blaster and coated it with Fluid Film. The 2 piece driveshaft and carrier bearing isn't bad in mine, but still causing a slight vibration 55+MPH. As soon as funds permit I'm going with a one piece driveshaft, roughly $600-$700.
That's all I can think of ontop of my head. They're real solid trucks, honestly it's a good buy. Even with an accident these trucks command a premium and it's right in line from what I remember when I was truck shopping.
