Junkyard Find: 1967 Chevrolet P20 Adventure Line Motorhome

Back in the 1960s and 1970s, quite a few Midwestern RV manufacturers would take new Chevrolet Step-Vans and build them into motorhomes. Most spent productive decades ferrying retirees between Michigan and Florida, then settled into long-term retirement in driveways and dirt lots, serving as homes for many generations of raccoons, possums, and wasps.

Here’s a Kansas-built P20-series RV in the San Francisco Bay Area, giving up some of its components while awaiting the cold steel jaws of The Crusher.

I couldn’t find much information online about the RVs made by the Adventure Line Manufacturing Company in Parsons, Kansas, though there is a bit of firearms-forum discussion about the AR-15 magazines made by the company a few years after building this vehicle.

RVs are always the most disgusting vehicles found in the inventory of self-service wrecking yards, invariably packed with hantavirus-saturated rodent detritus and bottles full of crank piss (or worse). I have spent far too much time in junked RVs, ever since I made the stupid decision to heat my garage with a Winnebago propane furnace.

The engine is gone, but it would have been a pushrod straight-six ranging in displacement from 194 to 292 cubic inches with an output between 120 to 170 horsepower. That’s right, this massive steel box got its motivation from an engine making horsepower very similar to that of a 2017 Corolla (though the 292 did put out 275 lb-ft of torque). Think about that next time you complain about modern econoboxes being underpowered.

I couldn’t make out the price on this tattered FOR SALE sign, but I’m sure it was nowhere near low enough.

Coming down the hill from Donner Summit with these brakes must have been exciting.

Made when men were men and California families vacationed in hoppy, clattery, leaf-sprung delivery vans.

    So happy to hear about your find! I'd love to have one myself. For pics and info, I'd have to talk to my parents, aunt and uncle and see if they have any pics or info. I am happy to do this, but it may take a while. You might post an ad in The Parsons Sun and see if any ALMC employees are still around. They may have some information for you.

    This Chevrolet P 20 adventure line is the closest we could find. I am trying to figure out what this motorhome was that we had when I was a kid. Would love to find one and restore it!

  • Theflyersfan I always thought this gen XC90 could be compared to Mercedes' first-gen M-class. Everyone in every suburban family in every moderate-upper-class neighborhood got one and they were both a dumpster fire of quality. It's looking like Volvo finally worked out the quality issues, but that was a bad launch. And now I shall sound like every car site commenter over the last 25 years and say that Volvo all but killed their excellent line of wagons and replaced them with unreliable, overweight wagons on stilts just so some "I'll be famous on TikTok someday" mom won't be seen in a wagon or minivan dropping the rug rats off at school.
  • Theflyersfan For the stop-and-go slog when sitting on something like The 405 or The Capital Beltway, sure. It's slow and there's time to react if something goes wrong. 85 mph in Texas with lane restriping and construction coming up? Not a chance. Radar cruise control is already glitchy enough with uneven distances, lane keeping assist is so hyperactive that it's turned off, and auto-braking's sole purpose is to launch loose objects in the car forward. Put them together and what could go wrong???
  • Jalop1991 This is easy. The CX-5 is gawdawful uncomfortable.
  • Aaron This is literally my junkyard for my 2001 Chevy Tracker, 1998 Volvo S70, and 2002 Toyota Camry. Glad you could visit!
  • Lou_BC Let me see. Humans are fallible. They can be very greedy. Politicians sell to the highest bidder. What could go wrong?
