Welcome, Dwight!
Since you're not in a hurry, one way to get a first hand look at a variety of "egg" types is to attend a
rally. Some have an open house time, but even if not, most owners are happy to show off their trailers. As far as I know, a non-molded trailer would be welcome to register and attend. Information is in the "Rallies,..." section of the forum.
Best wishes!
