I wonder if you or anyone else has taken a road trip w a hitch-mounted cargo tray like this one or this one along with a cargo bag. Hoping someone can report on the range or wh/m hit one can expect to see? I would expect nowhere near the hit a trailer would deliver, but if it's still pretty high that may make the difference between getting it vs. just talking the minivan for my upcoming road trip (and man do I NOT want to take the minivan!!) I poked around the road-trip sticky thread too, but couldn't find any trip reports talking about a hitch-mounted carrier like this. Cheers!
