did make something called an Add-a-room. There have been some for sale
on this forum. If you do a search you could find some pictures. Unfortunately, having one made is the most likely option, which will be very expensive, unless you can sew or know someone who does. Also the Add-a-room uses snaps to attach to the trailer, so if your Boler
doesn't have those, that could be another challenge.
Please post what you figure out, there will be many people who are interested.
