Candumy Portable Clothes Drying Rack for Balcony Windowsill,Folding Towel Rack Outdoor Retractable Laundry Rack

is there a smaller model?

Would this work on an RV ladder, for drying clothes while camping?

What are the four white (enclosed) clips for?

what does this mean?"The highest temperature of heat insulation is 70 degree." Can you have this outside if temp is over 70 degrees?
