Do you ever encounter a steep climb on the trail and wish you had a longer wheelbase for more stability? Or maybe you have a long wheelbase and get stuck on your transfer case and want a shorter wheelbase.
Alec Yaeger used to have these thoughts too, and they led him to build the Green Rock Dawg. This buggy has a bank of levers that control everything from wheelbase to ride height at each corner to steering front and rear. And this is actually a simpler system than the spiderlike hydrostatic buggy that Alec previously built and which he drove via a keypad.
If that seems unbelievable, consider that this vehicle is registered in Alec’s home state of Nebraska and he actually drives it down the road! “I get pulled over sometimes,” he says in his typical calm demeanor, “but usually they just want to take a closer look at it.”
We can’t blame law enforcement for that. We wanted to take a closer look at this out-of-the-box thinking as well. How does it work? Well, as they say, a picture is worth a thousand words. We watched Alex tackle some of the hardest obstacles we have ever seen, and he wasn’t even breaking a sweat.
