I usually take some kind of stitching when on a trip with DH. He likes to read in the evening. So I stitch, otherwise it's TV or games. One time I took the trailer to the coast, alone. I made a christmas pieced/quilted jacket while watching the ocean. It was too cold & windy to be out, but I was happy in my pull trailer.
I think it all depends on what kind of down time you have and what you like to do.
