If having two they have each other while you are away from the camper. My concern would be how much they bark while you are gone. My dogs do not bark so I am free to leave them in the camper with air conditioning
on. They have 5 or 6 x-pens outside hooked together, so they don't need to be walked all the time. The trailer is sometimes surrounded by x pens so they can be with us. They have their own fenced in yard, and have nice comfy kennels in the camper if we need to leave them for awhile.
I got my camper for their safety as well as mine.
