Yeah - looks like you're doing a good job with surfacing. That's an interesting vehicle.

I'm guessing that the THICK SURFACE problem is due to the offset distance being greater than radius of curvature (probably at the front or rear). You might have to take the Fill surfaces out of the Join, and just offset the middle section. Then manually create the inside surfaces at the front or rear.
