Diesel vs gas......................

I recently bought an 05 Chevy extended cab 4x4 3500 Dooley with the duramax and allison. Before I had an 01 2500 4x4 extended cab short bed with the 8.1 and the allison. I was unsure about diesels before I got one. I have to say that I enjoyed the 8.1 it has plenty of towing power but did not pull the trailer quit as easy as the duramax. I always had to pull the trailer 70 to 75 mph with the gasser to run in overdrive and was not able to set the cruise. With the duramax I'm able to set the cruise on 65 and let it go even up hill. I've never had a diesel before so I didn't have anything to compare with a gasser. I have 7,000 miles on the new one and recently got back from Leadville,Colorado I averaged 8-10 pulling and
18 empty. With the gasser I would average 4-6 pulling and 11-12 empty. I have had both now and definately prefer the diesel over the gas. If for nothing else but the ease of pulling.
