I have a 2001 Isuzu FTR with the 7.8 and Allison auto. It had 162k miles on it with a 26 ft dry van body. Truck runs great, but it has a cracked front plastic bumper from where I hit a bale of hay, a deer, and a bear (separate incidents, lol) -it basically looks like someone knocked out it's front teeth and the AC doesn't work. These truck usually go for 18-21k bucks in better condition. Rough wholesale is 12,550 black book. In pieces this truck is worth close to 16k. What should I ask for it?
