Yeah permanent alternations is fine for me. I was also thinking of drilling a hole, one on each side of the trim piece and inserting the rod ends and retract it till it stops.
I have a 98 Sienna and I bought an adjustable curtain rod but it wont stay secured because the trim panel isn't flat.
What's the best way to install and secure a curtain rod on a minivan?
I live in the Chicago suburbs and wont be able to escape the cold winter months. I wish I can but I cant due to work. I'm thinking using a medium size cooler and build an insulated box for it.
