I'm not sure how active this topic is but I just purchased a 1960 General Motors PD 4104. This coach appears to be in excellent condition with the exception of the power plant. It has a Detroit Diesel 6V-92TA with a Allison V730 transmission. The engine was over heated and the heads are cracked. I decided to remove the entire power plant and perform a major overhaul myself. The transmission is in excellent condition and will not need much. The entire coach was converted to a motor home in the late 70's early 80's. The coach has quite a few up-grades, full kitchen, refrigerator, stove & oven, micro wave, heating system, gray & black water systems, (2) Carrier roof top mounted A/C units, new invertor, Bathroom & shower, New tires, New Brakes, New batteries, New Radiator,(2) year old Onan 6.5 KW generator, Satilite system, solar panel to keep the batteries charged, power steering. I lifted the coach up in the air and inspected the entire under carraige and with the exception of one air bag it's in excellent condition. This is what I was told relative to the history:
1st owner: USAF Academy in Colorado Springs Co. 1960 to 1976.
2nd owner deceased: 1976 to 1981: converted unit to a coach.
3rd owner deceased: 1981 to 1998: converted engine from inline 6-71 with std transmission to 6V92TA / Allison V730 trans.
4th owner living: 1998 to 2014: added many items and used the coach on a regular basis until the engine oveheated.
I love the coach and intend on getting it back on the road better than ever. I would like to know if anyone knows the history of this vin number: PD41044993.
