Several years using the Kuat rack behind multiple vehicles (from a smaller Subaru Crosstrek to a pickup truck) on local rides and on long vacation drives, love it. Not cheap, but very sturdy and reliable and easy to use, get on/off and tilt down.

I don't have the addon for 4 bikes, but have used it when some touring cyclists were in town and carried their two very hefty e-bikes on it. Nice knob to adjust a cam that makes sure the rack doesn't rattle in the hitch receiver.

Not cheap, but in the same range as the others of same quality.
