We bought a new Solitude and are getting ready to head out on a trip that will take us over 2000 miles. I turned on the fridge to get it cold but the battery seems to be draining quickly. I am getting two days out of it at the most. I have also swapped batteries and get the same results. Is this normal for these trailers to drain the batteries so quickly? I am going to add at least one more battery but want to make sure I don't have something draining my battery that shouldn't be. Again, does your battery drain this quick?
