I travel with my two boys in a bigfoot camper. They are 100 and 115 lbs rottweilers. One sleeps under the table and the other in the hallway. You do have to watch where you are stepping but it works fine. They are great companions and great watch dogs. When I am in a warmer place I open the door and pin the screen shut with the stairs. The boys never touch the screen but if you are on the outside you know not to mess with them. Most of the time I am in a cool place. I use it for traveling while I am teaching in Southeast Alaska. Yes I use it all winter long. Two wet dogs are my biggest challenge, as trying to get them dry and get the humidity out can be difficult. How hot is the area you will be staying in?
