4x4 Evo: TRUCK.POD modification Thread

Hello!

I was working with 4x4 Evo patches earlier today and I noticed that both in the patch and the retail version, 2 identical trucks are different types. The Chevrolet Silverado and GMC Sierra, which are 100% identical except for the logos and names (same year, same engine, even the same frame) are listed as 2 different kinds of pickup trucks. The Silverado is listed as a full-size truck, while the Sierra is just listed as a standard truck. Is it possible to modify truck.pod to convince the game that my heavily modified GMC Sierra is a full-size truck, as opposed to a standard truck? Thank You!
