I bought the XTR1 for my ranger because the modularity of this system. I can attest to the build quality to this rack. I have already been able to test it out with a RTT and other attachments. Everything stayed tight and solid, even after some hard use. I would also highly recommend the off road brackets, it adds overall rigidity to the system and helps keep structural integrity. I would also like to make a shoutout to Xtrusion customer support. Those guys are on top of it, answered all of my questions and concerns mostly within the same day. Top notch customer service/ support, you guys are awesome. Thanks guys, keep up the great work.
