For ~10 years I've been using Kuat tray style rack, initially 2 bike and later upgraded to 4 bike. Kuat makes a wonderful rack, but these days our Kuat is in a 2 bike configuration and mostly used on my wife's Evoque. With the 4 bike configuration, the Kuat rack is heavy and unwieldy. Additionally, as mountain bike bars have gotten wider the bike in the first position is dangerously close to the LR4 rear window. On a rough road I've had that first bike hitting the rear window so hard that I stopped and wrapped a rag around the bar end just to save the window!
Last year I upgraded to
Alta Rack with 6 bike trays for the LR4. Love this rack! It nicely works with a variety of bikes, easily lowers to allow rear access, and holds bikes far more securely than the tray style rack. With the rack lowered, the rear window and tailgate have plenty of clearance. With the rack loaded it takes 2 people to put it up, but if you have multiple bikes on there presumably you have some helper(s) available...so no big deal.
The rack is HEAVY (approximately 70 lbs). For the OP this may be a dealbreaker, but it sure works well for us. I can install/remove it solo, but it is a lot easier with 2 people.
There is some debate between bar mounted (ie Lolo, North Shore, Yakima, etc) and wheel mounted (Alta, Velocirax, etc). Most of my bikes have carbon bars so hanging the bike by the bars scares me. I'm very happy with the wheel mount, including some rather rowdy approaches to trailheads. Bikes are secure and the rack handles rough roads far better than any tray style, especially for mountain bikes.
For times when I want more security and don't have more than 2 people in the vehicle, I use Kuat Dirtbag mounts secured to a piece of 80/20 aluminum. This provides an easily portable and adaptable bike rack. The rack simply sits inside near the tailgate. Bike goes in backwards, fork mounts to the rack, and all is nicely secured inside of the vehicle. I appreciate not having to worry about the bike being stolen, and on longer road trips in inclement weather the bike is safely inside. Of course not more than 1 rear seat can be used this way...but for just going out to ride with a friend or for going to a race etc it is perfect. Pics/details available on request.
