with just the two of us, we have the luxury of the whole back seat.  So, we have a suitcase each on the backseat of the cruiser, and a bag for dirty clothes in between it.  Used towels are always hanging over the back seat and suitcases to try and dry out a bit.  This works now, but when we take our border collie for a trip, lots of things will have to be rearranged. She will travel in the rear, on top of the drawer, which is a great area for her, as the cargo barrier shelf and divider make a great 'cage' that she can stand and move around in. Hopefully will take her for a couple of weeks trial run next year, now she just gets to go for day trips to the beach.  Hey , got off the subject a bit didn't I?  Oh, well.
