Love our new trailer
They listened to what we needed and wanted. Joy was super helpful (internet salesperson). She helped us get the trailer we wanted. The process was a bit slow, but I understand they are extremely busy right now. There was a bit of a delay with returning calls and email. The show room is awesome!
