Carrick Watson in a Champ. PCAU living quarters. 1950s.

The Champ was a useless Army machine, too heavy and too complicated mechanically.
Very hard to work on due to little space to work on, and too heavy in many situations - stay away from muddy roads with deep holes .

Champ was a bad Army vehicle, too heavy, complicated - and could be overturned easily. The Rolls Engine far too hard to access for repairs to be used for military use.
