I just got a new 10' Haulmark today. I've got a 96 Yukon 4WD That rides pretty high, but not jacked up. I need to install a trailer hitch under my bumper. My question is: 1. Will this be possible with my dual exhaust? 2. If so, who is the best between Reese, Drawtite and Valley? 3. What would it cost to have done by a pro? Thanks for your time and input.
