Pictures can be deceiving, but I do like the idea of comparison shots to check accuracy.
These two images may not be exactly lined up top to bottom, but they're pretty close. The wheelbase is just about right on, but the door locks are slightly farther forward on the blue truck.
Anyway, I think this shot gives the best example of what I was talking about with the rollbar. I also drew a green line on the red truck from the center of the rear wheel up through the body line and then copied that same line over to the blue truck.
Maybe I'm not helping? Hopefully I am. I copied the windshield over too.
Very cool build!!
