I'm new to the travel trail world. I have a 2012 Areolite 195QB that I picked up last year. Everything worked fine last year. This year everything worked fine going out, but on the way home the truck would not charge the batteries in the trailer. I have a Honda 1000 generator that would charge them just fine during the vacation. When I got home the power chord charged them. Can anyone tell me where I should look for the problem and how to fix it with out taking it back to the dealer and paying an arm an a leg for them to find the problem.
