I had a F350 crew cab, long bed, diesel. The wheel base was longer than the alignment racks at the tire stores. I always took it to the dealer for alignments.Thanks Gents. I went to the dealership where I bought it today and made the service guy walk outside and look at my truck and tell me if he could do it or not. They take pretty good care of me there, it's just a bit farther to drive than I wanted. If it doesn't work out I'll look into some of the recommended places.
After 3, one tons, I've gone back to 1/2 ton trucks. They are just a whole lot easier to deal with, ride a whole lot better, and nowadays have tow ratings similar to the older big trucks. No regrets.
Truck looks great VUPD!
