Trucks!? Which one is the best/safest/most affordable/most reliable?

[krisqh4]

Right now I have a Subaru Outback, love it but I want/need a truck (horses). So a hauling truck, also needs to be 4wd. 1500/150? 2500/250? 3500/350? Best gas mileage? Fuel efficiency will have an impact on my decision.
I've heard good and bad things about all trucks, and done a lot of research but can't decide. Right now I'm leaning toward Chevy Silverado or GMC Sierra. But what years? And would a Ford, Dodge, or Toyota be better? And if so what years of those trucks? So many questions, so many options!!
Please no answers of "Ford's rule!" or "Chevy's are the best" or "I'd rather be cummin' than strokin'" I've heard all of that, I need reasons, facts, solid and concrete! Thanks
P.S. Thoughts on Diesels?
I don't think I'm going to have much need for heavy hauling, so probly not 3500/350. But I'm going to need more power than a Tacoma, as great as they are I'm going to be hauling anywhere from a 2 horse trailer with one horse to a 5 horse trailer with 5 horses, so I don't think that will cut it. :P

I'm really considering a diesel. I've heard that diesel is better for the environment than gas, but I've also heard its worse. ???
I've also heard about installing a Micro-chip to enhance power and fuel efficiency. ???

Diesels get bad rep. They're actually just as fuel efficient at gasoline engines, but ultimately comes down to the driver.

If you're doing some heavy heavy towing, look to the 3500/350 model of a truck, you'll need the beefy rear end.

As far as gas motors are concerned, Dodge's Hemi kindof blows the other trucks out of the water for power.

As far as Diesel motors, Duramax and Cummins (Chevy and Dodge) both have great power houses.

It's really about personal preference, but definitely go with the larger size of truck.
