Towing equipment ends up being a lot of personal choices. Two of the big manufacturer's are Blue Ox and Roadmaster plus several other smaller ones. Both have web site with a lot of information about towing.http://www.blueox.us/http://roadmasterinc.com/
Motorhome Magazine is also a good source for introductory towing informationhttp://www.motorhomemagazine.com/index.php?s=towing&x=0&y=0
There is not going to be one correct answer for selecting towing equipment. Some of the things you might want to think about:
1. When the toad is disconnected for the motor home do you want the tow bar stored on toad or PC.
2. Weight of tow bar.
3. Base plate used on toad.
4. Drop hitch to maintain level connection between toad and PC.
5. Supplemental braking or not -- Big decision!!!!!!
6. Type of supplemental braking.
There is a lot information to digest before you are ready to buy.
I have had good luck with Blue Ox both the equipment and customer service.
Keep the questions coming. Everyone here is eager to help.
