Why does Dodge go cheap with their steel?

That is why I only have Chevy trucks
Chevy trucks rust so bad on the rockers and wheel wells. Trust me, guys at work have fairly new ones and rust rust rust. Another co-worker bought a brand new Ford in 2010, and it has rusted wheel wells. Here is my '01 Ram, 236,*** miles and no rust. Frame is black, like new! not brown. Yes, I live in a rust belt state.
