Now that is real service! Looks stout and very functional....I've never felt comfortable with those rack systems that cantilever a large number of bikes far off the vehicle via bumper hitch. The Kingston vertical style design puts the bikes/rack weight where it should be...not at the end of a long lever. I've also owned horizontal rooftop five bike racks for a van that was an absolute nightmare to use.
Looks like putting the bikes in (or extracting) would be very easy, with no need to do it sequentially. This rack style reminds me of how the SteadyRack storage system works....I've got five of my most frequently ridden bikes mounted on the wall in SteadyRacks in my shop, which makes them extraordinarily easy to access.
I've a lifelong mantra about stuff (especially recreational stuff like boats, RVs, and lake cabins)....things that are easy to use GET used. That's why there are always shitloads of lake places for sale (as well as storage lots, marinas, and garages/yards with power boats, trailers, and motorhomes that sit around unused and deteriorating for years).
