I think that Yank truck looks very much like this Leyland Martian, a ten ton artillery vehicle built for the British army in the 1950's by Leyland Motors. It had an eight cylinder Rolls Royce engine and did a very respectable 3 miles to the gallon. I knew somebody that had one and do you see that cab? You could organise a dance in there.

It's the vehicle size and weight that would give be concerns. lt's all right on hard surfaces for refueling choppers but we were never afforded that option most times.

We used large collapsing fuel bladders that could be removed from the vehicles and left on the ground or kept on the truck and used to fill four choppers at the same time. With the bladders a refueling truck didn't have to hang around and wait for the refueling to be completed before it went to another group maybe miles away to refuel them. Surprising to me who was a bit of a pessimist at first this system seemed to work well for us. Think of how heavy that vehicle is with a full fuel load of fuel. We were standing around in Germany talking to German soldiers in the field and when looking at their trucks I thought Wow are they ever built high off the ground. I asked one why are you trucks built so high off the ground and he says with a smile because the mud is deep in Russian. That give us all a laugh but it was true the more you thought about it.

Modern British lorries have a flat front with the driver sitting on top of the engine, as you can see next to the Oshkosh vehicle, US trucks have those "sticky out" fronts, I wonder why?
TSW also use collapsable fuel bladders where lorries can't go.

Probably using very large motors in the American trucks and that sticky out thing is where it's at. The engine under the driver is probably to save space and would shorten the over all length of the vehicle for British roads. Trouble is if you blow a piston or rod on a motor your sitting on it could end up killing you.

Oshkosh also sells baby and kids clothing.

But there not slugging it out going cross country over rough terrain or fording rivers like the ones the military uses. I seen a lot come through the block of a V12 rolls engine in our Centurions. Hard to snorkel a motor which isn't high up on a vehicle.
