I am honestly swamped with other projects on my motorhome that I am thinking of scaling back and just renting a UHaul trailer for the short term until I have the time to deal with it all.... The tow bar cost me $75 and the rental trailer would only cost $140. To save $1500 I can live with leaving my car behind on long-distance trips. For now.

Also, Roadmaster does not seem to offer base plates for ANY sort of Mercedes Benz vehicle, regardless of year. Mercedes is simply not in their database at all. My guess is that it was either a hassle they didn't want to deal with or they didn't want to sell a product that damaged the transmission without yet another expensive product that disengaged the driveshaft.

It also seems that it's illegal in NJ to tow any weight car without supplemental brakes. Oh well. A tow bar is out of the question. Harbor Freight is honestly useless.
