Welcome, Mike and Carol!
You've come to a great place to learn more about molded fiberglass trailers! As I'm sure you've already figured out, the challenge is to get a look at some actual trailers, since most do not sell through dealers or participate in the RV show circuit. There are three things you can do: (1) contact manufacturers, who typically maintain a file of owners willing to demo their units, (2) post a request here- you may find a nearby member willing to show off their trailer, and (3) attend a fiberglass egg rally
, where you can potentially see the greatest range of makes and models.
Your Tacoma could handle quite a few FG trailers, but probably not the largest Bigfoots and Olivers. There is some useful data here that may help you narrow down possibilities: Trailer Weights in the Real World
. Post #297 has a downloadable spreadsheet that allow you to sort, filter, and calculate stats.
