If you are buying it because of the mileage claims that you have heard....no. You will be disappointed in most cases. Although, just driving short trips, my truck now gets better mileage than my 1500 ever did on the highway. If you plan on keeping the truck for a long time, then you might want to consider it. If your trips for hunting and fishing are quite a distance away, then it might be worth it, but you can buy a lot of gas for the $6000 option. Upkeep is just as expensive on a diesel as it is on a gas engine....you just get a bigger hit on your pocket when you go to do it since you do the stuff half as much on a diesel (oil changes). After having my truck for awhile, I find it hard going back to driving gas vehicles. Now, if you have any specific questions, shoot away so we can help you out in this decision.
