I ran across an entry in a truck Encyclopedia years ago but havn't been able to find much more. The Duo-Drive 300A 6x4 was built in 1931 at their factory in Lima, Ohio. It had two straight 8 Lycoming engines side by side. Total of 275hp. If anyone has any information please let me know as I am obsessed with the look and innovative design. I hope there is at least one that has been restored somewhere. In my searches I also discovered the "Spangler" and the "Eisenhauer" , which both had twin engines and I would like to know more about them too but the "Relay" is the standout.

Thank you! I will. I never had that group come up previously - they look pretty good.
