Horrible experience took 3 weeks to process paperwork, the camper payment was due almost right away when I got the camper. sales man requested down payment right away before I had even seen any paperwork, then wanted more. Finally when I did get the camper I didn't receive one piece of paper saying it was mine. I still don't know who to make a payment to. First day using the unit in florida the a.c. junction box goes out and the floor is soaked with puddles from and unknown leaking source. This is a brand new 2018 mallard. I will never do service with them again.
