Thank you for the reply.
That's too bad about Tri-Glass. 38" wide would fit onto one of the narrow, inexpensive trailers from Harbor Freight, which we have. We currently have a rooftop cargo carrier on it, and have used it for a couple years that way. The Tri-Glass looks like it has significantly more cargo volume, so for an expanding family, that would be welcome
. I'll have to keep my eyes open. Since I am from Alabama, there may be a few around (I have never seen one).
