We are looking for a new unit for us to continue to full time in. The Solitude has caught our eye. We would love to get a factory tour as we feel it is the best way to get a feel for how well the units are made. My question is, do we need to make an appointment or do we just show up. We will be in the area 1/6/2014 - 1/10/2014. Thanks you in advance.
