How to Keep My Boat Trailer Surge Brakes From Locking Up

Question

Question:

I have a 2013 GMC Sierra 2500HD Duramax. When I put my truck in reverse to launch my boat or put it on the trailer the brakes will some times lock up. I know they’re surge brakes but don’t know how to fix it. My boat is a 2019 Malibu 24MXZ.

With surge brakes, you have a brake actuator applying the needed pressure to the brakes. In order to back up you will need to have a manual lockout or an electric lockout solenoid, like the Replacement Solenoid Valve # T4748800, which will close when you shift the vehicle into reverse, allowing the trailer to be backed up.

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

You are correct that this refrigerator does not have an ON/OFF switch or function. The best you can do is "Standby" that draws an unknown amount of power. One option is to pull the 12-Volt fuse at the RV power center. A much better option…
