I joined a few months ago. What a great site! I have learned a lot on here. Looking at other rides makes me want to do more to my own. I bought my '03 Silverado 1500 4X4 (stock 5.3 automatic) about a year ago. The next mod I want to do is a Flowmaster SUV exhaust. Another mod would be a headache rack for hauling long lumber. Any suggestions? I'm a carpenter and use my truck for work. I am also planning on buying a small camp trailer, 18'-20' 4,000 lbs. dry. I am wondering how well my truck will pull such a trailer. Doug.
