It is bad enough to have to make up a sofa every morning, worse still to have to do an air mattress.  After 5 years having not used it even once, we just pulled it out and replaced it with a reclining sofa set from Recpro.  We could still make the dinette into a bed if we absolutely had to, but that probably won't happen either.  If we have guests, they had better bring a tent along.  Or, a couple of sleeping bags to lay on the floor in front of the sofa.  Which is probably more comfortable anyway.
