Whats everyone using for Toad braking

I use US Gear's Unified Tow Brake (UTB) and couldn't be happier! There is nothing easier to hitch up and go, and since I occasionally tow in snowy/icy conditions, I especially appreciate the ability to control the towed vehicles brakes from the RV. The design comes with built in breakaway protection, charge line to keep the towed vehicles battery fully charged, and a vacuum pump that energizes the towed vehicles power brakes. The design also incorporates a brake light switch circuit that isolates eliminates the need to remove a fuse for proper towed brake lamp operation.
