We bought a 2009 Winnebago Class A gas system last year and just purchased a 2014 CRV to tow. We set up our dingy tow system as follows:
Brake - SMI Stay-In-Play Duo because it is permanent, only requires a cord to plug in and a switch to toggle to get ready. It uses both brake lights and inertia to activate which reduces unneeded TOAD braking.
Brake light monitor. We had this wired to and mounted in the RV dash so I could easily see when TOAD brakes were being applied.
Tow Bar - Blue Ox Avail tow bar with its associated base plate. It is their newest tow bar and is advertised to be not binding with a better turning radius.
Fuse. Since the CRV requires a fuse to be pulled when towing, we installed a Fusemaster disconnect so I only have to toggle a switch rather than pull the fuse.
This system is easy and quick to set up. To tow, we hook up the tow bar, attach the safety cables attach the brake disconnect switch, connect a brake electric cable between the RV and the TOAD, toggle 2 switches in the CRV, run the CRV through the gears in accordance with the owners manual, and then go.
