Not rear mounted , but roof mounted. I use the Thule ski carrying thing every Jan when I haul my x country skis up to the Highlands and seem to miss the snow every time . I have a 100watt solar panel which it doesn’t really interfere with ( we camp wild for several days with fridge and heater to run). I’m a shortish 5ft 8 , but can reach it easily when standing on the sliding door step. Carries the skis solidly and they don’t get as sh*t up if carrying them on the rear. I tried a home made version with my tow bar mounted Thule bike rack one year. Roof rails are also useful for shifting other stuff during non ski activities. Skis on the rear were also a nuisance with a tailgate.
