It may be this one that came from somewhere in northern AZ;
"This Kristi came from an old rancher that I bought my WW2 half-track from, he used it to haul feed to his cattle when the snow got too deep, I believe it is a 1957, the place on the data sheet where it was printed is gone, the engine data plate says it was built in 1956, the engine is VW and runs really well, it will need some fuel system work since the unit has been parked for around 20 years, I haven't tried to drive it because the bogie tires won't hold air, but the rancher said it was driven when parked, but you have all probably heard that before, the body appears to be crack free, the interior is in very good condition, the trailer is included and it looks like it is the original Kristi tilt bed trailer...."
The one that this describes was sold to someone in Durango in January 2010. Possibly the same one(?)...
