Why is Peterbilt backwards?

I have two friends who just got new Petes. One is a 379 and the other is a 387. both trucks came from the factory with the DEF tank on the right side. Why is this when every other manufacturer is putting it on the drivers side. Plus, all of the truck stops are equipping their pumps with the DEF on the drivers side. Seems dumb to me. That's enough to make me not buy a Pete. Even Kenworth has it on the drivers side. Don't they want to sell trucks? I guess we're going to start seeing Petes going backwards through the fuel islands on a regular basis. Bad planning there.

 

The 379 was ordered special right down to the tires and paint. The 387 was ordered by his company, but I would assume they were never asked. I know in the case of the 379, it came as a total surprise to him. His older truck didn't have DEF, and he didn't even think about it until he bought the truck home and I asked him about it. Now he's trying to find a way to run a fill tube to the drivers side. He is an intelligent driver with over 40 years experience. I'm sure if they mentioned it to him, he would have opted for it on the drivers side. Now he has to run to pay for the truck, and he cannot just give it back. Had he known, he never would have accepted delivery on it. It's too late now. My friend with the 387 said he's just going to go backwards through the fuel lanes when he needs to fill it up. Seems crazy to me. It should be the same on all trucks.

 

No way it stretches that far
