This has been coming for a month or so as I evaluated my towing situation and future uses. My current trailer weight was at the limit of my Dodge Hemi and I had a choice to make. Towing limit of the Dodge is 9500 lbs and I estimate my trailer is at that weight now and I could see it getting heavier as load up for my winter trips.
While the Dodge worked fairly well in the flat lands of the Midwest I know that the ride through any mountains would not be an enjoyable ride. I could have changed the differential gears to gain a couple thousand pounds towing but that would have also cut the gas mileage but reading shows that it still would have required a lot of time at 4500-5000 RPM range when climbing. So a month or so ago I started investigating getting a diesel.
I went and looked a dozens and in the vast majority of cases they had high miles and looked like they were beat to death. If I want a truck that would last me 10+ years I sure don't want to start out with one that already has 200K miles on it. Finally on Saturday I found what looked to be what I needed, in fact it was more truck then I really needed but I would rather have more truck then not enough.
It is a 2008 GMC Sierra SLT 3500HD Dual Rear Wheel Crew Cab with the Duramax diesel engine. It has every option available save for a couple minor ones (power pedals and rear window) with 80K miles on it. While a bit high miles for an '08 it still has a lot of miles left on it. After a few hours of negotiations we agreed on a price and I purchased it. It still has to go back to the dealer to install the hitch rails, spary in bed liner and front receiver that I had them throw in, then I'm ready to hit the road.
A short 60 mile trip empty got me around 19 MPG empty which is better then the 16 my Hemi got plus it should have a lot better towing mileage then the Hemi. At least the extra MPG will offset the higher price of diesel fuel. Can't wait to hookup the trailer and see how it does.
