VIN Number

 1964 Crown Supercoach   40 foot, 49  passenger coach

Note:       Being sold AS IS at the time of sale.  Will furnish new start and generator batteries at time of sale.  The coach has not been driven since 2017.   Fairly priced.  (do the math!)

Mechanical issues: (known)  can send pics of the “issues”. 

  • Water pump.  Antifreeze on pan beneath * (leaking gasket?…I have a gasket).   Recommend “fixing” before a drive.
  • Diesel fuel in oil (most likely leaking injector, per Wagner) …  drain oil and replace before driving. *  Have a Wagner report on this. 
  • Steers hard to left …Garrison Valve rebuild??  or Power Steering pump rebuild?? …Not a prohibitive issue.
  • A/C (basement- Coleman) needs service recharge.
  • Some older tires, but  many “look “good.  Some with very little mileage.  At reasonable speeds, would most likely get you “home”

PLEASE NOTE:       HOW MUCH  $$$  to do these things?  Have no idea;   (have it done, or do it yourself)  still a great investment considering price of RVs today!

  • Northern AZ University, Original owner;   we are second owner;  all original records
  • GVRW = 38,500  
  • Registered  26,000 by NMDMV

Excellent buy for the “right person”Great for a do-it-yourself-er.   I have done it for 20 years and am not a “mechanic! )

Selling only because I am a Senior.  Just can’t wheel it around anymore…or work on it . :>(

Great Coach!

From what I understand, there were only two or three of these  particular Coaches made…one for NAU and the other one or two for the Atomic Energy Commission in Nevada.

This coach is Diesel, NHH Cummins 220, side mount (pancake) amidships,  Turbo (265 hp), 10 speed Road Ranger, Jake Brakes,  Inter-axle Differential Lock  (8 wheel drive for snow and slippery road). 

Steel 10-inch chassis beams front to rear, aluminum skin over steel frame. (except for window level change out, 10 gauge steel).   1 million miles+-,  designed for 2-3 million.  Around 20,000 miles on it  since we’ve owned it (2001).  In-frame rebuild a by NAU about 64,000 miles prior to our purchase.   

We averaged around 10 mpg; 12 MPG high.  NAU stated 11 mpg. Smokes on start up; dissipates quickly.  A great ride!   Leather electric driver and passenger seats.

New clutch, new steer tires, others changed  as judged necessary;  new airbags (8 of 10??), new  starter, fuel pump, and radiator rebuild, brakes plus many other change-outs. Air lines checked prior to last drive (2017).  Started several times since.

Complete service records since new, original manuals and specs. Many pictures  available showing conversion methods  We used the coach regularly during the conversion process.

Onan 6500 Genset, new starter, Webasto Diesel fired engine heater,  2 fresh-water tanks (110 gallon total +-), grey and black water tanks plus toilet fresh-water tank; 110-gallon diesel fuel tank, two  10-watt solar panels, 3 heaters (rear ,middle front, work separately when Webasto is running, even when parked) , back-up camera, fog lights, search light, Co-Pilot wired, many extras: Lots of  parts, including paint and parts removed from original coach.


Cork underlayment front to rear over 1.5 inch Marine plywood sub-floor.  Parquet walnut floor to Bedroom (floor there needs final install); base trim needed throughout, steel framing in ceiling for two A/C units.

Cabinets and trim of Oak and Hickory, custom-built.   Shower, Commode (Marine), Lavatory and sink all functional; no known issues.    3 Cooling exhaust fans, Inverter,  Fridge, Microwave, Magic Chef oven / stove- 3 burners.  New hot water tank. Tilt down table.  Electric control panels easy access under counter end and in driver and trunk area. Excellent storage front to back.

Minor issues:

We full-timed in it (stationary) while building a “tiny house” in 2018-2020. Fresh water system altered a bit, (all lines available); hookup to outside water as is.

Needs attention  here and there…Little things, cosmetic mostly, nothing serious; just years of use.. Not pristine, but clean.  Would not recommend  driving till some things are attended to. (see *Above and below * )

Speedometer cable not hooked up, but “in place”. (We used GPs)

Body issues: (known)

  •  Driver windshield(cracked)
  • Passenger Windshield needs to be reset,  but is dry.
  • One side window cracked (prior to our purchase)
  • Rear window cracked
  • Paint chipped here and there.  (painted 2009 professionally)

Please ask questions.  Pledge credibility in our statements  above!  Bus is located in Southeast Central NM.

Due to my age, need to sell.  Price is firm…. AND A BARGAIN!    Somebody NEEDS this fine coach!

Thanx for looking.
