Welcome to the forum. If you want to connect the 10 watt panel without disconnecting the battery I think you're going t0 be dissapointed. That will not be enough power to handle the parasitic drains and mzintain the charge on the batteries. You will need to either disconnect the battery from the trailer or ADD a battery disconnect. If the trailer came with a factory battery disconnect it won't disconnect all the parasitic drains unless it has the brand new system that Keystone is rolling out.
