Patience Franklin,
Not every member comes here every day. And when the person who has all of your answers logs in your post may have fallen to the bottom. There are lots of creative members here. I'm not sure what percentage of them have opted for a Trillium. I suspect Bolers and Trilliums are more common in Canada. Scamps and Casitas are probably the most common brands in the US.
Lots of members have their websites listed as part of their signatures. Check a few of those out. Based on comments in their published posts, the honors for the most aggressive use of a FGRV probably go to Robert Brummet who was on an expedition to create a film documentary on farm life. (Correct me if I'm wrong here.) Lanny Webb uses his trailer for camping, fishing AND photographic retreats (

http://www.watsonmountain.com/Pages/nancy_art.htm) goes to art workshops using hers. There are craftspeople galore here. The great thing about FGRV is everyone has the ability to modify their rolling studio to suit his or her individual needs. Check out the mods threads to see some of this work.
I have a 16ft
Fiber Stream. I use my trailer to remove myself from my daily surroundings. Just putting myself someplace different is helpful to my creative process. Since I write, I just need a space to sit comfortably for hours, preferably but not necessarily with a juiced plug available. I should have pictures of my mods available by autumn, when I'm finished tweaking the unpolished pearl.
