Rockcrawling in a Classic 1977 Chevy K10 Isn’t Easy, But That Doesn’t Stop Grant ChapmanPosted in Features on August 31, 2018
Rockcrawling is a complex pastime. At one end of the spectrum you have JK Wranglers with 40-inch tires and coilovers that aren’t used for anything more than going to the mall and picking up the kids from soccer practice. At the other end you have Toyota pickups that have been rolled so many times they look like a crushed beer can. But most 4x4s fall somewhere in the middle of the spectrum, including Grant Chapman and his 1977 Chevy K10. Grant understands that sheetmetal limits where he can take his fullsize truck, but he willingly runs such trails as the Rubicon. Grant wants to keep his truck looking good, but if he happens to get a dent he understands it’s not the end of the world.
We can’t say we blame him, as this classic stepside is beautiful. The looks aren’t just skin-deep either. The truck features a stroker engine, an NV4500 transmission, an Offroad Design Doubler, and locked 1-ton axles. Grant doesn’t own a tow rig or a trailer, but living in Reno, Nevada, means that trails like the Rubicon aren’t too far away, and the Chevy goes down the road quite well. Grant admits that the truck was a basket case when he purchased it five years ago, but as he has upgraded and replaced parts it is nearly perfect. Let’s hope it stays that way.
