Looking forward to this build, as I might have to change plans on my 6x6 tractor build from a Globe to a R model. Spent a lot of years/miles in R models.
I hear that sanding these printed bodies down smooth for paint is a bear...

I'm using the F350 powered steer axle with F350 springs with factory holes drilled in them, and it does lift the front end up some. But so are the 1:1 6x6 trucks. I've seen some guys redrill the rear suspension mount holes lower down to get the frame to ride level. OK for a straight truck, but a tractor will be too tall to hitch up to stock trailers anymore, just like the 1:1. You just put blocks under the landing gear legs.
Yeah shapeways is where I got mine, I also got a few extras like MACK emblems and the bulldog for hood ornament. The prep work is a little bit tedious but really not that bad. Just take a couple days to get plenty of high build primer built up and sand after 2-3 coats seemed to work the best. I think I have a total of about 8 coats. I plan on using a nice automotive clear and helps hide alot of imperfections that aerosol clear coat cans doesnt.

Well this thread is kinda old, PB wont show my pics, so Im going to post pictures directly attached here.

I have not lost interest in this project and I am trying to build this a little differently than standard practice. Which is probably not the smart way, but I am tying this with my other hobby of casting and forming metal along with my 3d printer and design ability. So I am actually attempting to cast the majority of the dump bed from aluminum which is going well, although it is a pretty heavy dumper I think it will still work fine, I will modify my pattern to make thinner castings and maybe even make the walls shorter and use a piece of wood at the top like some full size truck do.

I attached some pictures of the process, the bed is cast from aluminum with traditional sand casting methods using petrobond sand and 3d printed patterns that I finished with primer and sanded down, the casting duplicate the patterns finish almost exactly, as this petrobond sand is MUCH finer than standard water bonded sand.
