Our pair know the single bed is theirs so they have a blanket etc made up so they either sleep on that or on the floor, but not outside - just a pain when they both are storing and the hubby too - I want to go outside in the car. We sadly lost our little 9yr old cocker on xmas day last year, she just loved the CT especially our bed as she could check out the passes by etc and we would often get a laugh from other campers who noticed her their, we really miss our Hollie Girl. :'(
