The trope about the family packing into the SUV or four-door pickup and heading to the mountains or lake for some camping and family bonding makes my head hurt. There are precious few that actually can do that and not leave the campsite ready to murder each other. The kids are going through electronics withdrawl and are grinding every last possible nerve with their constant complaining. Mom is not having any of this back-to-nature crap and just wants a hotel room with a hot shower, basic cable, and take-out pizza. That’s her idea of roughing it. Meanwhile, Dad, the one person who should be enjoying this trip, is so agitated and frustrated that he’s contemplating the consequences of leaving all of them in the woods and starting over with a new name. He would, too, except their 2019 Suck-O-Lux 3500 with the optional butt-massaging chairs and wi-fi hotspot is currently the rest of the family’s living accomodations. Gotta love the great outdoors, right?
Thing is, there are families who honestly do love going out into the woods and seeing things that are well beyond the tourist traps. They go to the mountains, they scramble up desert trails to gorgeous outlooks over vast basin territory. They go to small seaside towns and camp on the beach. Or maybe they just take a trip back to the family property in farmland country and let the kids pitch tents and camp out at the far end of the field for a night or two. It’s those types of people that this 1974 International Harvester Wagonmaster is for. The four-door pickup is the hottest body style on the market…if you are making trucks and you don’t have one, you’re losing. In 1974, this was a freak show. Based on the Travelall, what would be considered a four-door full-size SUV today, the Wagonmaster was simply that minus the roof from the rear door to the tailgate. IH’s claim was that this was the rig to haul a fifth-wheel trailer around with, but note that tiny bed…guess what couldn’t happen. It wasn’t that International was in great shape anyways, but having the motoring press kick you when you’re down over a bad claim didn’t help. 
This 392-powered, four-wheel-drive example is a handsome beast, utility be damned. It won’t haul a fifth-wheel, but it’ll easily pull a standard trailer just fine, with a bunch of kit in the bed and several people inside, enjoying the plaid benches raided from a Scout. Today’s four-door trucks are pretty much full-size sedans with a bed and four-wheel-drive as an option. Meet the truck that pre-dated those cushy units by at least thirty-some years.
They actually were suited for fifth-wheel hitches. I recall at least one from my youth. The upside of a 392 was torque for days. The downside was they made 454’s seem thrifty. Less refined than a Ford pickup, more refined than a USAF-spec Power Wagon crew cab.
In retrospect, they were about 25 years ahead of their time.
