Some truck enthusiasts lament the fact that modern-day pickups, especially heavy-duty trucks, have gotten so bloated and big – but today’s production pickups really have nothing on this custom-built 1950 GMC cab-over.
This truck recently rolled into MetalWorks Classic Auto Restoration’s shop in Eugene, Oregon so it could solve some electrical gremlins the owner was experiencing with it. This truck is known as the “Mother of All COEs” – a title that it rightly deserves, in our opinion, as this is certainly the biggest cab-over-engine rig we’ve ever laid eyes on.
The truck was listed for sale on eBay about 75% finished back in 2013, according to a post on BangShift.com, but it seems someone scooped it up and invested the money necessary to see the project through to completion. It is based on a modified 1988 GMC Topkick 6500 chassis and is powered by a 636 cubic-inch Caterpillar 3208 diesel engine, which was completely reworked during the initial build process. The lower bodywork is all custom and features integrated steps for easier ingress and egress into the 1950 GMC cab, though it would still require a fair bit of effort to pull ourselves up into this high-riding beast.
According to the BangShift article, the “Mother of All COEs” also features a 30,000 lb gooseneck plate and rides on 22.5-inch Alcoa transport truck wheels. We can’t imagine the owner does very much towing with this truck, though. If we had to guess, this unique custom creation is only ever taken on leisurely cruises and maybe the occasional car meet or auto show.
