A couple things to look for on Trilliums:
1. Brown(dark) staining and moisture in the storage areas below the seating benches. This brown would indicate leaking around the
windows or along the back belly seam. While you are in the benches, there is
fiberglass wraped plywood on the floor and should be inspected for rot.
2.
Axle condition, there's lots on this subject here but age is probably a good rule of thumb for replacement. If its 20 years old, it will need replacing.
3. Frame condition. Early
Trillium frames were prone to cracks in the area where the frame emerges from under the
fiberglass body in the front. The solution is a doubler welded on to the frame in this area. Look for the doubler and any cracks. Also inspect the frame for straightness, no visable warpage.
4. Check for door fit and whether the door hinges are loose.
These are just a few of the biggies for Trilliums to supplement the list.
I do have a question for you. Was it your Mom or Dad that named you Mo22?
Good luck, Dave.
