Nice - I have been looking at what would be a better tow vehicle to use instead of the "wife-required" suburban we have now, which, coincidentally, replaced the 1/2-ton model we sold to get a 3/4-ton to tow our new RV. How do you like the 5.9L Cummins, what tranny do you have, and what kind of towing fuel economy do you see? What trailer & how heavy? I found a 2005 SLT in nice shape for sale nearby with a 5.9L Cummins & a shell on the back, which might sway the wife's desire to have enclosed cargo area. I want to get an idea of what the actual cost per mile will be with diesel vs. the cost per mile with our current gas TV.2500 Grunt wrote:
Detailed professionally :), payed off and only 110,00 miles 2005 Dodge 5.9
I now tow a TH that weighs 9000k dry and 13k loaded (scaled) and the truck tows better than my older TT that we no longer have that weighed 8000k loaded because of the flat front of the TT. Fuel mileage: per the computer, towing now it says 10-11mpg at around 65 flat highway. I like this truck because of a couple of reasons. It is pre emission meaning it does not have all of the extra mandatory emissions BS which yields better fuel mileage and breathes better IMO. It's payed off LOL and it has a long bed with a proven 5.9 engine. It also has the 48re auto tranny. I am on my 2nd transmission and I bought it with 30000k miles on it (2nd tranny installed at 70000k)and now have 110000k. If I was to consider what you mentioned then I would take an oil sample and send it out for an analysis for $20. That could tell you the condition of the injectors among other things. Also look for the "shuttle shift" possibility of the 1st into 2nd gear hesitation issue. Looking at the front end is another area to consider specifically ball joints. If you are really concerned about fuel mileage then I'm not sure a diesel is the way to go? 10-11mpg for diesel at $4/gal VS. 7-8mpg gas at 3.75/gal. You have to pay to play. Good luck!
