That's pretty neat to see your vintage picture of the old red and gray van. It's a blast from the past for me. Your first van was an old "Haliburton" 4x4 "Treater's Van".
When I graduated from college in 1981 I went to work for Western Company of North America (WCNA) in the Texas oil patch. Western was one of Haliburton's competitors in the oilfield services business. Western also had a bunch of 4x4 vans in the Rocky Mountain region that were also built by Pathfinder. I must of purchased at least 50-60 of those vans from Western in the 1980's for resale.
At least all the Haliburton's trucks/vans were decent colors in red and gray. All of Westerns vehicles were all "urine yellow"!
