I ’m having a hard time wrapping my head around GM’s axle ratio on the trail boss/At4. I always order my trucks and I would like to order a diesel half ton. You can only get 373‘s in a Chevy with a diesel off-road package that’s the only way you can get them, you can’t get them in a GMC at all. I happen to like the Chevy better than the Gmc but you can’t get a diesel Trailboss! Why does Gm not want to sell trucks? Not everyone just buys something off the lot because it’s pretty! They have all the parts, I’m not asking for something that doesn’t exist. I just want it built the way I want it built ! This makes no sense!
