Dodge, GMC, and Nissan compete on this small hill climb (100% grade) at Spring Creek Off Road. very muddy and slick; who will make it up? Dodge and GMC are on Nitto Terra Grapplers. Nissan is running Michelin LTX A/T2. The Nittos on the Dodge are old and bald; the Nittos on the GMC are nearly brand new.
