We tow a 2013 Ford Fiesta with a 30' class A that is about 1,500 lbs under GVWR but I prefer to tow with an aux. brake. We had the SMI Stay-N-Play system installed. Yes it was expensive but it is so convenient and efficient that I feel it was worth it. I had the active brake light ran to the front of the coach and mounted to the dash so I know exactly when my toad brakes are activated. A great feature and piece of mind knowing the brakes are working when needed.
It did take some special wiring to get the brake light in the coach working with the Fiesta battery being disconnected but if the installer calls SMI techs they can explain an easy "work around". I love my set up!
