The NASCAR rivals have gone in significantly separate directions, with Bowyer designing a '50s-style work truck based on the Tundra and Biffle coming up with the flashy off-roader pictured above. Roush has fitted the SVT Raptor with items like their TVS2300 supercharger system good for 525 horsepower, a performance exhaust system, custom 18-inch wheels shod with 35-inch BFGoodrich tires, TireGate tire carrier and light bars front and rear.
So what determines who built the best truck? The winner will be decided by the almighty dollar, with both trucks going to auction for charity. Bowyer's Tundra already sold at Barrett-Jackson's Orange County auction, raising $100,000 for the Emporia Community Foundation, while Biffle's SVT Raptor will look to beat that number at Barrett-Jackson's Las Vegas event in September.
