Our Stealth Hitch has been awesome. I installed it on our Hyundai Palisade with no problems whatsoever. We used the rack-receiver option recently to carry 5 bicycles carrying about 125 lbs on a Curt luggage rack for a 1000-mile trip. Since all connections are really solid I could barely tell that the bicycles were there (except when backing up!).
I love that it is completely hidden when the hitch rack receiver or towing ball are not attached. And everything about it seems very robust and of the highest quality.
The only thing I did not love about it was running/attaching the extra wire to the battery for the wiring harness (used when towing). While this feature makes the system much more robust, it was pretty tricky running the included wire under the Hyundai Palisade. I actually found the optimal run to follow the center of the Palisade under the spare tire to avoid threading it through the rear drivetrain/suspension. Once past the rear drivetrain, I was able to run it under a very large undercover panel (I think in parallel with brake lines). I also added extra heat shrink tubing at all mounting points (of which I mounted the wire with zip ties to at least a dozen locations). Finally, it was not obvious where to thread the wire through the engine bay to get to the battery. I think I threaded it close to where the brake hydraulics went up into the engine bay. With all the extra twists and turns the supplied wire only had about 4 extra inches of play by the time I got to the battery. Finally, I slightly modified the battery cover with a small slot to allow the lead from the fuse connection to safely and easily be attached to the positive battery lead. While the hitch mechanical installation itself was very well documented, the electrical left a bit to the imagination.
