Welcome to FGRV, Tina. You're in the right place.
One of the oft-repeated myths of fiberglass trailers is that they weigh under 1000 pounds and you can tow them with just about anything. One great resource on this site is a database of real-world loaded towing weights: Trailer Weights in the Real World
. Post #297 links to an Excel spreadsheet that can be downloaded, sorted, filtered, and used to calculate averages. That, combined with the towing information in your vehicle's owner's manual, will help you get started.
Molded fiberglass trailers have some distinct advantages over conventional framed trailers. The lack of seams means fewer places for water to enter and cause damage. As a result they tend to last longer and have much better resale value. And they are generally lighter than framed trailers of similar size, even if not as light
as some claim.
One disadvantage is that they are mostly sold factory-direct, so you can't just go to a local dealer to look one over. Egg rallies are one way to see a lot of different models in one place. Some have a time set aside for open house tours, and even if not, most owners love to show off their trailers. There is a map here: https://www.google.com/maps/d/viewer...Y.kH9EkyWon6YM
. Another, if you have a specific make or model in mind, is to contact the manufacturer. Most have a network of owners willing to demo their trailers for prospective buyers.
