You can talk theory all you
You can talk theory all you want. But, go tow all day with a Toyota or a Chevy V6 gas motor. Then go out an tow with the 2.8 Colorado diesel. do this for few weeks look at your gas bills, and how you feel after dealing with the gas motors each day....You will pick the diesel....There is a reason why all the big trucks use diesel motors for hauling trailers....Diesels are better Truck motors for towing and hauling weight. You may not get some of the fast acceleration by winding up the motors like the V6s. But, most driving does not require that type of approach. My 2.8 diesel has no problem passing comfortably....
