If you are at least fairly satisfied with the tow capability of your I5 1st Gen truck, I think you will be downright giddy with a 2nd gen truck. The V6 may behave a bit differently than typical "truck" engines, but it does a nice job. And when you aren't towing a trailer, you will feel like you are in the lap of luxury with a nice looking truck with much better gas mileage than that old Silverado (for at least a little less money up front.)
I know a lot of the 1st gen guys are very happy with their I5 engines, it just is hard for me to imagine such an engine. Was at least half the reason I never looked at a 1st gen seriously, it just gave me the image of a half-hearted attempt at an economy truck.
