Calmark makes a cover for casita
to specs. I know they'll make you one to your trailers specs exactly if you send them a photo and measurements.
I'm sorry but I don't know enough about trilliums vs. casita
for design. Maybe someone with more knowledge can chime in here to give you advice!
I'm good with the EBay cover, although many have experienced disintegration in blazing sun. Where do you live? I'd much rather get indoor storage so am looking for winter months.
I am alone without help here so I find putting the cover on myself much too difficult but if you have help it goes ok. Hence I don't cover mine in summer when I'm camping frequently.
