To make sure co-driver Casey Trujillo points Loren on the right path, which many drivers struggled with this year, a Lowrance HDS-7m GPS map is used. It features a 16-channel antenna, 6.4 inch LCD screen and SIRIUS Satellite Weather. This is actually an older unit that has been discontinued by Lowrance and has since been replaced by the HDS-7m Gen 2.

When it comes to the King of the Hammers, you need the best wheels and tires that are both designed for crawling with lugs on the sidewalls and wheels that will take the abuse of rocks riding against them. For tires, Loren’s choice was the Nitto Trail Grappler M/T in a 40×13.50R17 LT. Yes, he is using a 40 inch diameter tire that is 13.50 inches wide with a 17 inch diameter wheel. When looking at the rig as a whole, it doesn’t even look like they are that large but the numbers don’t lie.

Crawling up rocks is tough on any compound of tire, but the compound of the Nitto Trail Grapplers ensured that despite slipping on rocks, the tires never failed due to loss of tread. There were actually zero tire failures on Loren’s rig and his confidence that there wouldn't be meant that he did not need to carry the weight of a spare.
