I have just finished setting up our mh to flat tow a 2014 Corolla. I purchased the base plate from Roadmaster and also decided to install the Roadmaster Invisbrake. Have not towed much distance but so far it is a great setup. Have driven the Corolla about 300 miles without problem. We did have a dolly before but getting a Prius onto the dolly presented problems. Had to put blocks under ramps and if raining it would slip going up ramp.
If you decide on Invisabrake make sure whoever installs reads and follow the manual.
