Here's the deal....I have an '03 1500 silverado single cab, short bed on 20's. It has a 5.3 V8. My dad has an '01 1500 ex-cab with the smaller motor (forgot what size). I have the option of switching trucks with him. My truck is still stock only thing done to it is the wheels and tires (not much). His already is lowered, has a system, and will eventually have 20's. I'm most likely going to lower it and put a system in as well...but i dont know if i should switch. My friend says i should...but i'm still thinking. Does anyone have any opinions on what I should do and why? Thanx a whole lot. Here is a pix of my truck and his truck (before the 20's) so u can get a visual.
