That's a beautiful piece of work! Any reason why your rear tires are on backwards?
Actually I went and had them filled (beet juice) and when I was going to remount them I had a little thought. The V pattern on a tire is there to clean-out the mud as you move forward, but in hard pack, rock, or loose sand/dirt, you get better traction running tires backwards (its from my buggy/offroad days (consensus proven)). Also if I do get into a muddy situation (only once so far)....I usually am smart enough to back out before it's too late....my tires work better in the mud going backwards...which means my stupid self driving into the mud can't get as far and actually have better traction to reverse and find a new path....
I'm a bit of an oddball who doesn't conform to much.....
