GM&GMC MID SIZE TO GET DIESEL 2015

I'm very excited about the new diesels coming to smaller trucks in the US. I run 137 angus cattle in the middle of nowhere AZ. 95% of what I do can be done by a small diesel. I only need the 1 ton diesel to pull the cattle trailer in to the livestock auction. The 1 ton is too expensive to drive everyday miles and miles on end so it just sits there until it needs to pull a heavy trailer. I will be test driving all the new diesels (colorado, ram, and the titan cummins). However I prefer the reliability of toyota products. A crew cab 4x4 TRD with a small turbo diesel would be the perfect truck for what I do EVERY single day. I know many like me that are also excited for the new diesels. For several years I have been anticipating buying a new tacoma double cab 4x4 trd when the next redesign comes out but if the tacoma isnt sporting a diesel (from what I have read it likely will not) I will seriously consider the diesel option of the other brands.
