I won't be pulling a trailer much if any at all but will use the bed often, but not huge loads by any means.I owned a 1500 with the 4.3. I was impressed with the engine for about 3 months.....I was pulling a very small lawn trailer and mower at the time. It just wasn't enough engine in my opinion for a full size that did anything but commuting. If you plan on using the truck for truck purposes, get one with the 5.3l. the 6 cylinder in fine for a daily driver though. When I bought the 4.3. it was all I could afford. Just my two cents having owned both.
