I went ahead and ordered the Tesla Roof Rack today, and my next order of business is to find a solid Cargo Container to mount to it. Has anyone had any luck mounting Thule, or Yakima storage containers to the roof of their Model 3 - using the Tesla Roof Rack System? - I realize that these vendors produce cargo boxes that are generally compatible with most installations, but it doesn't hurt to ask. - I'd like to make sure that I'm adding at least an additional 15 Cubic Feet of storage (perhaps even 21) and still have clearance to open the rear trunk while mounted. - While I'm at it -- is there any significant difference between brand name companies, and the cheaper versions available online at Walmart, aside from aero-dynamics, and one-sided vs. two-sided access? The brand names can run an additional 300-400$, and I'm wondering if the difference is worth the extra money. Most of the time, these will be in storage, and we will probably make use of it up to 3 times per year. Thanks!
