When your slogan is “We make big look good,” you better not be a little guy or show up to an off-road event in a Geo Tracker. Luckily, Offroad Design’s Stephen and Brandon Watson are plenty tall and their wheeling rigs of choice tend to be fullsize GMs. Known for their now legendary NP203/205 Doubler and a full line of classic and late-model GM parts, Offroad Design came ready to wheel, piloting a work truck special turned hardcore wheeler. Their finely tuned fullsize had no trouble keeping up on the tight and twisty Jeep trails.
