Hope y'all can give me some advice. I have 2004 Silverado 2WD 4.3 V6 towing a 2010 189FDS. Have been out a few times with no problems, but they have been short trips, I stay at 55mph or below and have yet to drive on interstate. My friend who was with me when I bought the truck specifically as a tow vehicle for the TT said it would handle it, no problem. But after reading many posts re: towing, I'm not so sure. Thoughts?
