We purchased a camper from a private party and were looking to get setup for the 4th of July. The service department was able to take time and go over the ins and out of my new to me camper and also install a solar charging system. I can’t Express how grateful I am and when it comes time… I will not shop anywhere else for our next camper!!! - Thomas
