Last week I shared a group of mostly light duty trucks parked in a yard near Espanola, New Mexico. Today, I’m sharing a group of mostly heavy duty rigs I saw on the east side of the Taos Mesa on the road to Raton and parts north.
However, this group includes some trucks dating back to a time when heavy truck manufacturers were more regional, and trucks were built to meet differing regulations from state to state. I’m not sure I’ve ever seen those COEs (Cab Over Engine) before, so I decided to take a closer look
This Kenworth is a 500 series “Bullnose,” and appears to have been produced from 1948-1956. According to the interwebs, this early COE did NOT use a tilt cab, so techs accessed the engine through an engine cover in the driver’s compartment. I did not find any production numbers, but it seems this was a fairly common model back in the day.
In contrast, I did find production numbers on this Mack W-71, and it appears to be 1 of 215. Several different sites referred to the W-71 as “Super Rare,” and one site said only ten still exist.
Mack did build a few sleeper cab W-71’s, but this is a standard cab model with a sleeper box added by a third party.
Like the Kenworth cabover, this Mack COE did not include a tilt cab, forcing techs to work on the engine through the mail slot opening present under the truncated hood.
