Congratulations on your tandem Trillium
5500. We live in Alberta and have had our 5500 for 7 years. I have done extensive renovations to it.
Made the back table into a permanent bed.
Shortened the bed and added cupboards
added under bed storage
added corner shelves
Added TV, Microwave
, took out oven and put in Air conditioning
Added gray water tank
Removed toilet and just use a Porta Potty
Installed bike rack and storage at back
Added dual Propane
tanks to front along with the spare tire
Added new tail lights
I would be interested to know if your 5500 has leaf springs or torsion axels?
What tire sizes?
How much space between tires
between front and back of wheel well?
Are the tandem units on a separate frame of on the Trillium
If you photos of what we have done there is an old post of ours on this site, or I can send more pictures.
Keep in touch
