I'm thinking of getting a 2001-2003 F-150. One, to pulling a trailer with all my lawn mowing tools. Two, to plow snow in the winter. I'm not really familiar with rear ends. So should I get a F-150 with a 3.55 or 3.73 rear end. What are going to be my positive and negative aspects. I know i'm going to be getting the 5.4 V8 in it though.
