The other one that is pretty popular is the maximus-3. This was the one I was looking at too. They don't give an offroad rating, but the dynamic rating is 300lbs, which is about 80lbs more than rhino's on road rating. The thing I liked about this rack is that it looks like it uses two bolts instead of one to hold the feet on. The thing I don't like about it is that it comes with the pioneer platform so I don't know if crossbars are an option. I also didn't like the fact that you couldn't take it off the jeep. The last thing I didn't like about it is that the platform is huge where you will need to relocate the gps antenna with a bracket.Are there any other racks/platforms on the market that bolt onto the hardtop, while still allowing decent payload capacity AND easy hardtop removal using the TopLift Pro removal system?
I think Frontrunner is another brand that is just a clone of the maximus-3, or maximus-3 is a clone of the frontrunner. The frontrunner doesn't even specify a load rating; just says use your own judgement.
