I was reading Civilian use of the M274 Mule and read that The California Forestry Services received several years back (70's maybe) free from the Government to help with Forest Fires probably came out of Camp Pendleton. I don't know the Speed of these, but I bet it was just to deliver men and supplies not too close to the line. Here's one that someone took a picture of and posted it. Now that would be just right to fix up for the Ranch, but the pic looks old.
