New to towing a dinghy so....

Any reason to choose one over the other?

Chip,

While I cannot speak to either set-up on a Beetle, I have seen MANY installations of each on an a pre-2006 Miata.

On a pre-2006 Miata the Blue Ox baseplate mounts WITHIN the open grill of the car.

The Roadmaster tow bar attaches about 6" farther forward and about 6" above the location of the Blue Ox attachments.

A good friend had the Roadmaster baseplate on a 2003 and was towing it whith a Winnebage that had an EXTREAMELY long overhang (distance between the rear wheels and the tow hitch).

Rightly or wrongly, he did not use an auxillary brake system in his 2,200# Miata. No Brake Police please.....

During a 6 wheels locked-up and sliding emergency stop, as the RV rear went up, the car tried to dive under it. Because of the longer lever-arm, this resulted in the Roadmaster baseplate being bent down about 15 degrees.

Other than that one emergency, he never had an issue, but he removed the bent Roadmaster and installed a Blue Ox.

If you use a brake in the car, you would probably never have an issue, but I would look at how each of the baseplates mount to the car. Then get a tow bar of the same manufacturer as the baseplate.

Personally, I tow a 2012 Miata and use the Roadmaster baseplate on it and our 2011 Equinox.

I second the get one that mounts on the rear of the motorhome. I used a blue ox adventa II with a brake buddy braking system.

Any of the major brands. Look at each's installation and see what fits you. Looks like you have done this.
I would suggest a MH mounted tow bar. This will put most of the weight of the bar on the MH. The Roadmaster Falcon would be my choice for you.
After installation of brackets and tow bar, check height to make sure it is within the installed manufacturer's range. You may need to get a drop mount.

Whichever one is the simplest to attach to the car frame is the one I would go with. I've had both of them.

I have Blue Ox and it is easy enough.
