Vintage RV & Motorhome restorations - "The GMC Coop"

The Co-op: Road Test- 1973 Revcon 250………

This was an interesting road test that got a great deal of attention while driving.  I’m doing my 37mile road test run to give my graces on drivability of this super rare classic.

Revcon was formed by Wally Burnams son-in-law I think many because the Airstream founder would not consider the idea of the Airstream moniker on a motorhome…..he was a trailer man and did not believe in Motorhomes.  In later years he formed Argosy to make them and then relinquished to call an Airstream a motorhome in the end.

This is an all thicker aluminum than Airstreams, was assembled with exterior. Olympia rivets, used the Olds Toro drive train with a rear single drop axle with fat 12″ tires

(Ah, my phone decided to get contrary, lets see if Mr. Lap Top will cooperate

(There ya go baby, Mr. Lap Top is up!0

Continuing….. The slightly sanded brick shape is kinda standard for the day…..this is the design the GMC was determined to reshape.  To try and keep this report from being boring to you GMCers, I’m going to compare the Revcon to the GMC as I go….. With the many GMC’s I’ve been acquainted with, I kept comparing things myself as I drove.  Actually its a bit of give and take…..follow as I go through this.

Actually the first impression was sitting in the original low back bucket seat, with the odometer showing

(go figure, Mr. Lap Top worked once, now the phone is working again?)

So yeah, before detailing out the dash in our finals, you can see the odometer and I thing its real!  But the seats…..I think original material in that it matches perfectly the covered dash material.and the matching buddy bucket seat on the passenger side look cool

I mean the ride was pretty smooth but I’d bring a whoopie cussion until the original dead foam in at least the driver….but probably both get replace.  See, the seats looked like one of the hi points in the really clean interior……they are clean and look great but…….

BTW, I listened to a report on NPR that malineals feel putting”……” at the end of a sentence is a sign of confusion and something else….can’t remember so maybe its true…….so I’m spilling some of my lotus aperandi …….it’s what I do!

Back to the report, our mods to this awesome machine included all the things we do to the GMC to update thing with the 455 Olds motor.  It now sports FiTech fuel injection.  We have the control panel dash mounted for good constant viewingwhere I have the 4 function readout screen set to show constant vacuum, air/fuel ratio (AFR), coolant temp and dc voltage.  The volt meter is reading @ .5 volts low pulling ignition probably from a multitude circuit. But its cool to watch engine efficiency and what the computer engine management systems are doing to the motor performance.

Now “performance on a lightly sanded brick is not as robust as the same drive train in a GMC, there is much more wind noise even at lower speeds and acceleration from a light first leaps because of the fuel injection then aerodynamics takes over and gaining speed is a struggle but it did barge its way up to speed on.Road vision and the original Olds skinny when made for a pleasurable ride though with that vertical windshield you felt like you’re driving a trolley car.Ssteering was nice, the alignment took and those 12″ wide 16.5″ radial tire after trying made for a smooth ride even though my butt was squarely resting on a flat metal plate on the bottom of the seat!

On the drive I kept getting looks especially when I pulled them off the traffic light….like I said, it WILL go but air stops fast forward progress at a point…..you don’t run into that with a GMC and you certainly do not have the wind noise.  To appreciate that fact of a GMC, you need to drive this.  The replaced dash AC (an under dash unit from Revcon had to be moved over for a place for the radio.   This made the far left vent barely reach the driver…..I was sweating!  and yes, that’s a lighted blue USB port for the passenger……Handles well and is a good ride Roth the new Rostra computer controlled electric servo cruise control.And after uncovering the mouth sized from are scoop and building a tube epoxy texture coated bumper and those LED projector lights the front look is menacing!seeing that in your rear view mirror……

Original Revcon factory colors I think this coach had to have spent its life in a museum and now with state of the art additions this is a badass motorhome!  No doubt!Wwith the interior mods added……Honda water cooled generator, Avonite counter tops, hardwood floors, Quisenart convection, microwave, grill…sunken euro-sink this is a badass machine inside and out.

If you find one of these….windshields can still be had, its not a GMC but it is useful and sure create a a scene wherever it goes!  It was an honor and a pleasure to bring this puppy to the road

Hope this was interesting, see you tomorrow
