Yes some of the people from Stealthhitch are the same but they don't want to or not willing to support the old product that they worked on. They just wants to push/recommend their revised hitch. When they go out of business also then the stealthhitch's people will be in the same boat as us invisihitch/execuhitch owner!!!!
For those considering new hitch, you might want to consider big company like U-Haul, Westfalia, BMW, etc. For example U-Haul hitch are not fancy or cool looking, but longevity and easy of replacement parts maybe a plus. just my 2cents
