Otto, you hit solidly on some good points. I still drive with 6 volt on my 53 truck, for the reasons you stated. Recently had to replace an 8 year old battery, a slightly weak 6 V battery will tend to show itself earlier than on a 12 volt system it seems. These trucks have room enough to run two 6 V batteries in parallel.
