This is as a NEW motorhome with 13,000 miles.  

The Interior is completely modernized and is in NEW condition.

The Exterior is like NEW with complete paint and moderization.  

Production data indicate that 549 23 foot transmodes were built in 1976. Of that number it is unknown how many were sent to or acquired by Coachmen. There were a total 1016 23 foot transmodes built between 1,975 and 1978 (4 years). GMC stopped doing 23 foot interiors from those years 1975 to 1978. The only 23 foot GMC interiors were from 1973 to 1974 where a total of 629 were built. The total 23 foot GMC production for both transmodes and Birchavens was 1,649. There were a total of 12,921 GMC motorhomes produced for those 5 years of both sizes. This makes the 23 foot motorhome extremely rare given that the production represents 12%. Consider that it is estimated that less that 8,000 units of both the 23 and 26 footers remain of the road out of 12,000 produced (cannot confirm this number, but thought to be accurate)
