I was meaning to say that those trucks would likely suffer the same outcome a lot of battlefield equipment does, break down, get destroyed, but further to the point cannot be easily replaced until the late 40's, and that was without war.

The Red Army was indeed the largest force in Europe, much bigger then the 4 million strong Allied Force, but the west enjoys several advantages. They do have better C3I control, allowing them to respond much quicker, and call in support. Soviet Artillery had greater numbers, but western artillery was far more accurate and could serve the soldiers far better due to better communications. The Soviets due hold a slight advantage in tanks, especially when the numbers are factored in, the West wasn't using the M4 of Normandy anymore either though.

The Air Force though is a major difference, the Soviet air personell training was just on par with that of near-end war Germany, so any pilots the Soviets lose can in truth not be replaced, whereas the West would enjoy an able pilot training program that had been setup during 4 years of war (6 for some). Those Soviet pilots racing to meet the Western onslaught are facing a well-trained and very experienced enemy. The Western Air Forces generally had a less stunning record at tactical bombing becuase they covered an entire front, usually it was all done at a Strategic level, whereas the Soviets tended to mass a large percentage of their Air Force at one point where a breakthrough is made. This is almost suicide to try against the west, who have the majority of their air-to-air fighters within range of Soviet planes, unlike the Luftwaffe (The majority of which was destroyed by the west).

And as shown by this war, aerial superiority is a decisive factor, so that is what happens to all those Soviet divisions, in all likelyhood they will push the Allies back, but they will suffer huge losses at the hands of ably serving artillery, Allied air superiority, and at some points, Naval artillery. Eventually Soviet industry will be re-geared to fit the needs presented without the lend-lease yes, however it will severely cut into other production, and not come close to the Western industry. And the Soviets do have a slight problem keeping the supply routes from their factories open under an Allied air attack.

The only way I can see the Soviets being able to defeat the West is to get very very lucky and eject the Allies from Western Europe, and with some more luck on their side the Indians will be sick of hearing the British telling them they will grant their independence, after this war, and rise up, ejecting the British. Under these conditions, the only hope the Allies have is an operation that would dwarf D-day, becuase wherever they land they need to land a large force, as the Soviets will move a lot faster and have more soldiers then the Germans ever did. On the other hand, the Soviets can't win this either, even moreso as the Allies always have the Uber-Normandy to cling too (I can't say with any definite thought that something like this would never happen, after all, that's what Hitler thought and look what happened). But the Soviets cannot invade either the US or the UK, they simply lack any form of major transport to get across any ocean, and in the face of the Western naval dominance, the only way to break the deadlock is some kind of peace treaty.

So the Soviets can win by a peace treaty after overrunning Western Europe, and the West can win by holding the line in the first few opening battles, after that it is just a matter of time before the Soviets lose, General Winter will not save them as it had from the Germans, the West as mentioned before had a much better system of engineers, had a motorized supply system, and probably the best supply system in the world, and Soviet numbers will eventually be evened out, and it is likely many of the Eastern European countries they overran would continue partisan actions to get the Soviets out, aided by the Allies these have a serious chance of succeeding (Didn't the polish Free Army defeat the Soviets in at least one battle).
