No sweat on the dates.. Research is kinda my thing, and I enjoy hunting down info, so I'll gladly do what I can for you guys...
I chose the Ford AA since it's a late 1920's early 1930's vehicle which might (stress might!) have been in China. I could leave the tanker part off and make it a flatbed with drums. I just googled Ford AA and saw a nice 1929 Ford AA that is the same as the UM kit except for the fuel tank.
It's conceivable, so I say, why not? It would likely be that, were a vehicle used, they'd just pump the fuel right from the drums on the truck... At any rate, were I the line-chief, that's what I'd do if there was a flat-bed sittin' idle, some coolies hangin' around with nothing to do, and a buncha aircraft to get fueled quickly... No reason to believe that a few Ford trucks weren't in Burma and China here & there...
