Actually, I haul plenty. I tow a boat and regularly haul loads of fire wood and furniture along with other debree as well as a lawn tractor and generator. Nothing heavy duty, that's why I have a light duty truck. I forgot to mention that I did more than just the level. I took the 2" blocks from my 2003 Silverado and installed them on my new truck, replacing the 1.25" blocks, so my truck isn't actually level by the measurements. I do have some rake, it just isn't the 2.5" to 3" rake that most have. So mine doesn't sag, I agree I don't care for the sag that you get from a front level alone, don't think it looks good at all. I also don't want a 4" or 6" lift, while it might look good, the functionality of a stock height truck is what I need. It takes a lot more weight for my trucks rear to drop 2.5" or 3" from hauling something, more weight than I usually haul so for me it works. Can't speak for others.
