I am learning about pop up campers and am now considering a hardside. With no personal experience using a pop up or hardside, why doesn't an indoor shower seem to be a priority for manufacturers to install in only the largest pop up models. There seems to be enough floor space and height to make these an option. Are they not convenient, or too small to be a hassle? Many people recommend an outdoor shower, but that doesn't seem like fun in the rain, in cold weather, with mosquitoes, setting up, eventually standing in mud, or risking a fall. If you have a hardside without a shower, do you wish you had one?
