Welcome to the forum, Kim & Co.!
I think most of us here would agree with your conclusion- molded fiberglass trailers are great!
If you haven't already, I'd recommend starting your research by reading the towing section of your vehicle's owner's manual carefully and looking over the data in this thread: Trailer Weights in the Real World
. Post #297 links to an Excel spreadsheet you can download and filter by size, brand, etc. These are actual scaled weights of trailers loaded for camping. Manufacturer's dry weights and sellers who quote them can mislead.
You can visit the classified section here and also at Molded Fiberglass Travel Trailers For Sale | Fiberglass RV's For Sale
to begin to get an idea what's out there.
And if you have questions, ask away! Best wishes in your "egg hunt"!
