About the Blog: We started RVing in 2019, but did not decide to start blogging about our experiences until 2021. So, we have some catching up to do. We’ll sprinkle in some new present-day stories as they happen. But if you have time, start at the beginning. You’ll learn (and hopefully laugh) a lot.

How to Fix a DEAD BATTERY on Your Towed Vehicle?
When RVing, there are some travel days that are long. Do you know what makes the day longer? When we pull up to a campsite, and the battery to our towed vehicle (a 2019 Jeep Cherokee Trailhawk) is dead. In this video, Kasie tells you how we FINALLY fixed this recurring dead battery problem.
When RVing, there are some travel days that are long. Do you know what makes the day longer for us? When we pull up to a campsite, and the battery to our towed vehicle (a 2019 Jeep Cherokee Trailhawk) is dead. This kept happening over and over — usually when we took trips of 4-5 hours or more.
Our first temporary fix was to buy a portable battery charger. That worked, but was a PAIN! And, repeatedly draining a car battery is not good for it. Thus, we were on the search for a real solution.
In the video below, we share our permanent fix, which was to install a charge line between the RV and the Jeep. The charge line basically charges the towed vehicle battery using power from the RV.
Problem solved? Not so fast.
Unfortunately, the charge line fix resulted in another big problem: the breaking system on our towed vehicle (the Roadmaster Invisibrake system) was engaging when it should not. For example, one time, the Invisibrake system engaged even when the Jeep was not connected to the RV! After Kasie conducted some research and troubleshooting, we believe that was because current was backfeeding to the Invisibrake system from the Jeep battery itself. To solve that issue, Kasie installed a diode. Confused? We’ll explain more and provide the details in the video.
