Pop-up campers show their age quicker than others due to the canvas tent sides. If these sides need to be replaced, you can often order replacements or have a local canvas shop create them from the originals. If you don't want to restore the pop-up, you might want to look into selling it. If that doesn't work out, consider giving it away or donating it. The best solution is to get it into the hands of someone who wants it and wants to restore it. If you can't find anyone, you'll have to look into harsher methods of how to get rid of an old RV, like scrapping a trailer for parts and metal.
