Like the above said, its based off your needs...
If you just want to attach some recovery boards or a roof top tent, then a basic aluminum flat rack all go for under $1,000, see LFD or Prinsu, Victory, etc etc
If you want a basket to store wood, small items, coolers, bowling balls, whatever... most go for under $1,000.. see Yakima, Baja Designs, etc etc
If you want a mesh basket but also want to put a RTT on top, the best of both worlds so to speak...that’s the one that costs you close to $2k, and Gobi is one of the few, if not the only one, in that niche market and that’s what people usually go for because they want that cargo stability and RTT capability....all those flat rats wont be able to handle any cargo that isn’t overland “attached” specific like maxtrax boards and hi lift jack, any cargo that’s not apart of that, lol good luck keeping it up there.
