I bought the yukon because I got a sweet deal on it. I love the room it has to haul stuff and people, and it's all covered. Plus it looks cool and is great on the highway. It cruises at a good clip and is decently smooth compared to a leaf sprung truck.
I need to trade it for a crew cab diesel pickup though. I need a tow rig for work. Many times it's impractical for me to take a dump truck. It is inefficient and it ties up a truck that could otherwise be working. I also want to have the nav, xm radio, leather, heat, ect that i'm used to in my truck while I'm at work.
