I use 2 small pieces of velcro around the edge of the window frame and on the insulation (it is so light that is all it requires to hold it in place even while traveling). I can easily remove them and store anywhere since they are flat. It mounts to the inside of the window and then I pull the curtains over it. It really helps keep the weather out and maintain the temperature inside the rig and as an added bonus blocks out almost all of the outside lights at night. Here is a pic of the sheets. I suppose you could cover them with fabric or pillowcases to make them "pretty". Re: What did you do to your Class C MH today??? sjptak wrote: 3-14-08. I bought it.
