I have a 82 PA 30 footer, Have fun. My front AC unit was hanging by 1 bolt and the other one was lose about 10 turns to tighten. The rear was lose but not to the extent of the front one. I could only see 2 bolts on mine. No leaks though I took of the schrod off to clean the filter is how I found out they were loose.
How about some pictures Please!
