Hello. My wife and I are sorting out options for a travel trailer & pull vehicle. We believe a 23' Airstream (6,000 GVWR) or something of the similar length & GVWR would fit our needs. Our intent is to travel 3-4 months/yr and do not wish to be deterred by the Rockies or other obstacles. The vehicle we believe would serve us well would be a 2x2 GMC Sierra 2500 Crew Cab w/ standard bed. Engine choices are the 6.0L gas or the Duramax diesel. It appears the 6.0L should have the 4.1 rear end vs the 3.73. Please tell me if I am incorrect, but I believe either engine will comfortably do the job. Other than confirmation that the trailer/vehicle is a good combination, can you also give me an idea of the expected fuel MPG of the diesel over the gas engine while towing in an "average" terrain and conditions. There is an added cost for the diesel which may not make sense for what we plan to do. Thank you for your guidance. The variables in order to go RVing can be a mind boggling.
