I'm very happy with my Xtrusion Overland rack. Prior to it, I had a Front Runner rack, and prior to that, a Yakima Overhaul HD.
Each had their pro's and con's. The XO rack is the most modular. I went from the Front Runner to XO because I wanted additional height. The Front Runner rack is about 9" high; the XO 18" (The Yakima has an adjustable height).
The low height of the Front Runner was a blessing and a curse. On the positive side, it kept my tent below the Ram's roof, reducing wind noise and drag. On the other hand, it made getting into the bed to get stuff out harder, and I wouldn't have been able to mount that Offroad Solar Shower Tube under the tent like you see here.
The biggest pro of the Front Runner rack was that it was the easiest of the three to put on and take off. With the XO, I've accepted the fact I'll leave the rack on year round, especially now that I've run wire from that black box on the side into the bed of the truck. The box serves as a junction box for wiring for lights, as well as for running power from solar panels on top of the tent to a charger and battery inside the bed.
