Any suggestions about inflatable sofa bed in TT?

We have had our 2013 Keystone Bullet for almost two years and have never used the inflatable bed attached to our sofa because it is so complicated and seemingly useless. We like the sofa, but for a bed we vastly preferred the old jackknife-style sofa in our previous TT. Is there anything that can be done to make the bed functional or do we need to try to take out the whole unit (sofa) and replace it? lizzie
