The best way to power the interior lights in your trailer is with its own independent battery. You will not want to use the breakaway battery. The breakaway battery is only designed to operate the breakaway and will drain extremely quickly,…

The problem with cheap testers like the Tekonsha #6562 and similar testers is they can be hit and miss when it comes to working with different brake controllers. You really need a tester like the Hopkins #HM50918 for properly testing a brake…
