Tyco US-1 3208-2 Interstate Delivery set was a variation of the 3208 and likely sold in late 1985.  We have a discussion on our forums that explains why this late variation contains set revisions that are not indicated on the box and can only be determined by looking inside. The instruction sheet will indicate whether it is a 3208, 3208-1 or 3208-2. The final two versions are not common. They contain desirable, rare track pieces. The bad news is that no double turnout is included in the 3208-2, as in the previous two models. Instead, there are three High Adventure B3030 switched turnouts, as seen below. These also included green controllers instead of red controllers. It also included the Goodyear Dump Bin from the Motor City Trucking set, instead of the brown dump bin. This was toward the end of production of US1 Trucking and this was likely done to clear out overstock warehouse pieces from the GI Joe Set and Motor City Trucking.

-3901 Red Peterbilt Truck
