I thought that with damage like that the frame would be bent and the vehicle totalled??? 6-8 weeks is an average for a body shop. If they tell you 3 weeks you will hold them to that, but if they say 12 weeks and deliver in 6 then you would be even more excited. I had a car with minor fender repair and it took almost 4 weeks. I had another with suspension, bumper and fender damage 3 years back and they took 8 weeks. When I picked it up it the supension was still off. had to have the work finished at another dealer. Your truck looks in bad shape. I hope they have her running like a champion sooner than they quoted. Good luck.
