4 years on a K9 - full length 2.2M rack with a 250lbs RTT on it. Thousands of off road miles and its not budged a MM. The no drill rack was important to me since in Oregon it rains a lot. I also liked that it has more feet, dispersing the weight across the roof.
The only negative is the instructions don't say shit about sealing the bolts that use the stock mounting locations. Which ever rack you go with do yourself a favor use butyl rubber to seal them up. Many use silicon, but the wrong kind of silicon can accelerate rust (threads on here about it).
With the T-slots on both racks you can mount almost anything and I believe the FR and K9 accessories should cross over.
I ordered from Equipt in Utah and it showed up with in a week of ordering. I also ordered the High-lift mount which comes with parts to mount flat on top or to hang from the side. I used the side mount parts to fashion up a fairing using my maxtraxx. Which worked quite well as a fairing since the RTT is obviously flat sided.
I would order this rack again with no hesitation.
Lastly Aluminum is awesome- no rusty powder coated steel on my roof.
