There are dozens of different manufacturers, many of which, like Tote n Tarry, are long gone, but their trailers live on. On the FGRV website, click on the tab at the very top that says "manufacturers" to see a list. They are divided into those currently in production and "legacy" brands, like
Burro and Tote n Tarry.
I believe Tote n Tarry falls into the "Boler-clone" family, which includes quite a few that have the same basic shape, layout, and construction (2-piece, single-layer shell joined horizontally).
Boler itself,
Scamp,
Casita, Trail Mite,
Love Bug, Minit and
Perris Pacer fit into that category.
If you are determined to look only for a Tote n Tarry for nostalgic reasons, you need to prepare for a lengthy and far-ranging search, as they're relatively rare. It wouldn't hurt to post a wanted ad here and on fiberglass-rv-4sale.com.
Of course, everyone knows that the best brand of
fiberglass trailer is...
the one parked in your driveway.
