I found a pop up camper posting on Craigslist which recently dropped to $1,200 and they added this sentence to their posting: "The ABS roof is failing which is common for this model. However it is more of an aesthetic issue and it is not leaking." The interior is remodeled and we really like most everything else about the camper. Do you think this ABS roof issue is worth the $? I don't mind putting in the work if it's something I would be able to fix myself.
