Camper awnings are often attached via a rolling bar that when a crank or button is pressed, it will roll up the awning and keep it protected and enclosed in a metal rod.  There are also supports that when attached to camper awnings, will hold them up against the side of the camper.  Often it is just two bars that are needed.  If you camper does not have a mechanism like this attached to your camper, you can rig up a camper awning yourself or remodel one from an outdoor home and garden supply shop.  All you need to do is set up the awning as close as possible to your camper side – the side with the door on it.  You may also want to add a small tarp over the area that may be exposed that is closest to the camper.  To protect from rain and other weather elements.
