I'm in the market for a truck to support my family of 4 + 1 large dog for all sorts of typical outings. If you were in my position which trucks would you be shopping for in terms of make / year / mileage, etc.? I live near the mountains in Colorado, so 4x4 is a must.

Edit: Love the replies and appreciate the wide range of suggestions. I'll do some research into some models I hadn't previously considered and see what sticks. Cheers
