This customer wanted a very basic and afforfable system for staying out long weekends without plugging in somewhere. In actuallity a small trailer like this with this system has the potential to keep the batteries charged indefinitely if they are carefull and it cost less than 800.00 installed.
2014 Lance travel trailer
