The  mobile stage SL255 is an SL250 mobile stage with 8 added decks, and an added “batwing” to the roof to make it a full 32 x 32 covered deck.    We have the only full 255 in Atlanta on our lot.   There are a few other ways to add the decks, but the accepted way is to add 4′ to the front and 4′ to the back.   Mobile Stage Rentals (MSR) uses a bunch of these.   Most the the SL250’s that you rent from Mobile Stage Rentals are outfitted to be SL250 or SL255.
