The typical camper tentage is not designed for more than occasional use. Rain and, more importantly sun will kill it. The stitching in the tentage is very likely to be damaged by the sun. Sunbrella fabric is only offered in a very few campers and holds up well in the sun but even with Sunbrella you still have to watch the stitching closely.
Murphy's Law on Tent Damage also indicates that the longer the tentage is exposed the more likely you'll damage from other sources as well to include wind and animals. I would personally close the beds at the site for physical security as well.
