Being a retired automotive and component engineer (mainly for pickups/vans/and SUV's - working vehicles) and an engineering business owner for decades, it really concerns me that so many RV'ers and forum posters DO NOT understand the actually function required/demanded of tow vehicle brakes and the towed RV's brakes and how they must be adjusted and coordinated together.
The tow vehicle's brakes are only required to bring the tow vehicle itself to a stop, not the towed RV also. That's why towed RV's have their OWN brakes and why they must be capable and adjusted to stop the total towed RV's weight even faster than the tow vehicle. Including the towed RV's tongue or pin weight! The RV's brakes MUST be adjusted to always pull backward when activated on the tow vehicle to prevent any jackknifing scenario when bring the total RV rig to a stop or slowing using the brakes! Whether it be a panic stop or and normal use stop. NEVER should the towed RV's brakes be adjusted or incapable of allowing the RV to push forward on the tow vehicle when braking or stopping. It's asking for a disaster and a total lack of control of the entire rig.
THINK ABOUT IT!!!
