Mitchell Merta M. M. Mitchell M. 29-03-2020 Hummer H3 Slimline II roof rack Staff is amazing and Super knowledgeable.. I called the company to make a return because I thought I had a wrong part. I spoke to a Karston Koberg and never thought I could call a business 1(800) number and talk to an expert on my specific roof rack and roof top tent. Karston explained exactly what I needed to do, what parts I needed, and exactly how to do it. My rooftop tent is now installed and ready to go! I plan on doing all my future camping business with Off Road Tents. Thanks again!
