I would buy the Chevy. According to market trends, the Dodge has a lower resale, or residual value. This is purely my opinion, which is based on observations that I've made in the new and used car markets.
The ONLY way I'd buy a Dodge Pickup is that it has to have the CUMMINS diesel powerplant. This historically tends to be one of the FEW Dodge trucks that hold their resale (residual) value.
