Don't know if they're exactly terrible, but they are inaccurate. The Italeri American Superliner and US Reefer trailer. Truck has too wide of a cab, wrong frame, wrong suspension, wrong steering, and a few other things. Trailer is wrong height, no fuel tank, too large hubs, wrong location of leveling legs. However, they are otherwise great kits in that they have great detail and build up nice.
