WOW! This truck is giving me a boner. Excellent work, those 3rd members are awesome, and you realy got my brain thinkin hard about writing a program for the CNC i work on and trying to take a stab at it. I am anxious to see your final results, bigger is definetly better. I bet you could practicaly sit on this thing and ride around like a Power Wheels. If you need any pneumatic parts for the steering let me know, i have a bunch of paintball gun pneu's, something may work. If your lathe would support the stock, i would be curious to see what you could do if you tried to make your own beadlocks.
Very impressive work, its inspiring.
