considering you can get a new dodge cummins for the same price as a tundra i would go with the cummins..
story..
towed a sti to so cal for a car show last summer, flat bed trailer and car weighed in around 6k... buddy had a brand new tunda, towing a supra on a flat bed weighting about the same... best he ever saw was 12mpg and couldnt even pull 65mph up the sisque mt pass, i pulled it at 85 no problem and worst mileage i saw was 18.2 driving about 75-80 the whole way..... went thru half the amount of fuel he did...
