Review on 63124 Eclipse Black 2 Inch Carrier by Joe Calabro

I like the luggage rack, it's quite sturdy but the only problem I have is that I only have 3 bikes can accommodate. I just don't see how it will fit 4 bikes unless all bikes are road but no 4 mountain bikes will fit. Update: 25.02. Just used a few weeks ago, sack to LA and back, no problem, very durable. Now I just bought a hitch lock: https://www.amazon.com/gp/product/B07SYPMVVT/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 and because of the built in nut that goes in it my locking pin hitch doesn't fit. I just wanted a lock so I don't have to take the whole rack off and put it in the car when we ride bikes for security. Now I guess all I have to do is tighten the screw that goes in the nut and hope it doesn't get stolen. If there is any advice from the manufacturer or any buyers of this rack I'm open to it. :) Many Thanks!
