Four Wheeler's July 1969 issue took us to a special part of the desert where the Devil vacations when he needs some heat.

Visiting the Yuma Proving Ground and the LeTourneau Overland Train

Just north and east of Yuma, Arizona sits the expansive facility known at the time as the Yuma Proving Ground. Its location makes it favorable for year-round testing with higher-than-average temperatures and some of the lowest precipitation levels around (in 1968, 1.2 inches of rain fell). The Yuma Proving Ground allowed the Army to subject its vehicles to extreme temperatures, deep water crossings, onslaughts of silt to detect dust intrusion and resistance, rocky ledges and punishing washouts to verify structural integrity, and even drops from supply planes.

JEEP OR BLAZER BUILDING

JEEP OR BLAZER BUILDING

I was hoping to pick your brain as to a couple of different builds. I have a '19 Jeep Wrangler JL and a '74 Chevy Blazer. I'm a little baffled as to what to focus on. The '74 full convertible Blazer is my dream vehicle. She's been a long build and now I am thinking of focusing my energy on my wife's '19 Jeep JL. I recently joined a Jeep club and have been going off-road with a few guys. I'm shopping around for lift kits. Would you suggest that my time be spent and focused on the Blazer or enjoy the Jeep? I really can't do both.
