I've got the same airbag setup in my coach, hated the time it took to set up and tear down those silly things.
I just replaced mine with a hide a bed frame and mattress, we love the quick convenience.
Just measure the inside of your couch and order the frame kit from homeplacegroup.com, was here in less than a week and took maybe an hour to install. Mine cost around $600
If you decide to get one, PM me and I'll give you all the particulars to get it set up.
