The Gaz-MM (the AAA was an anti-aircraft platform) was the war time version of the Gaz-AA that had no front bumper, wooden doors with sliding widows, a single headlight and welded flat fenders instead of stamped rounded ones. The only real improvement was the engine from the Gaz-A Emka which gave the MM 49hp as compared to the AA's 39hp. The AA was a license built Ford AA 1.5 ton single axle duel rear wheel truck and was 5.3m long and 2m wide. The Soviets said it was 3.3 tons but this is likely do to different criteria. 3300kg was probably the max for the AA/MM under ideal conditions. The US-6 (studebaker) was a 2.5 tons (US weight conventions) under any conditions. It was a dual axle dual wheel truck though only one axle was powered hence the 4x6 even though it had 10 wheels. The "short U1 version if the US6 was 6.3m long and 2.4m wide withan 86hp engine. I have included a pick of each plus the Zis-5.You can clearly see the front axles of all 3, only the US6 has a pumkin
The Zis-5 was the same size as the Gaz-AA. The Soviets did make a medium truck in the same family as the US6 called the Zis-6, which was a lengthened Zis-5. They made 21,000 of them in 8 years. Postwar the Soviets copied the US6 as the Zis-151 but not until 1948.
