Welcome, Mary and Frank!
Since there are no dealers, there are two ways to get a first-hand look at a molded fiberglass trailer.
One is to attend one of the many
fiberglass egg rallies around the country. Some have a designated time for open house tours. You might join the
rally in a tent or stay nearby and drive in for the day. Contact event coordinators for advice about scheduling a visit. The
Lake Casitas rally near
Ventura is coming in a few weeks.
The other is to contact the manufacturer directly. Most have a referral program to connect you with a local owner willing to demo their trailer. Downsides are you have to have some idea of which model you want to see, and you only get to see one at a time.
Best wishes!
