Good call on the diesel. If you need a 3/4 or 1 ton truck, I don't think there's any other option besides the diesel. Add in any towing and diesel is mandatory. Around Colorado, elevation and hills are the norm. I'm a Ram guy and the Cummins tows 10,000lbs up and down mountain passes at 10,000+feet elevation with ease and can pass Subaru's while doing it. There is no replacement for a turbo diesel.
