So...we went and bought an energy management system to help protect the trailer. Kevin installed it himself and did an awesome job! So far we have saved ourselves twice. That's two times that we could have had our electrical system fried on our trailer. That is something that is NOT covered by a warranty. For something that seems so critical, you wonder why they don't already come installed? It seems really silly that you spend a lot of money on something that could be ruined in a matter of weeks if you don't have an energy management system installed.
