My husband and I just bought a 2016 Heritage Glen 272RL. The previous owner passed away and the daughter didnít know much about the trailer.
There is a black switch to the left of the slide out switches and water tank testers that we canít exactly figure out. The air conditioning goes on and off when I switch it and it also has to be on for the fireplace to work. My guess is that it is used to switch from battery to A/C power but Iím not 100% sure. Wondering if anyone else knows for sure. I can post a picture of it if needed. Thanks in advance for your help.
