Hi Dave and Paddy;
We have a '78 Trillium 4500 too and we swear by it. Maybe some of the pictures on our web site will help you get an idea of what these things are all about.
Thanks Ken and Di for the link to your Trillium
photos - your mods and decorating are superb! I noticed that you painted your Trillium
several times... did you do this yourself? What type of paint
I was so glad to read in your slideshow that you bought back your Trill and that it's now back home with you!
