We have a 2010 Surveyor SP-293, the air mattress is folded up under the fold out couch, factory sloppy leather protection liners did not cover the sharp rods around air pump storage area, we had many holes on the first night. With pictures and a strongly worded memo we had the mattress replaced under warranty.
I repaired and covered all sharp corners and the second mattress was folded under the couch. On the first night using this new unit it leaked. I found the pin hole, patched it, and decided it was not practical to fold up this matress under a couch in such a tight manner. Therefore, we removed the mattress, put it in a storage bag and placed in the storage compartment under the master bedroom mattress.
We reccommend not folding these mattress into tight areas.
