I have a 5th wheel and everyone says I pull my house around with me. For your questions on a pop up I have two friends with them and they enjoy them alot. They have know problem with the heat in them, they warm up well and if you get the new fabric you will have no water problems. The only thing they both have said in lines of draw backs is that you can not just pull into a sit late at night when its raining and jump into the camper you have to set it up while everyone sets in the tow car. I told them the kids should do that after all you brought them along. "lucky kids"
