I'll take more pics of the water tank fix when the sun comes up,..
but here's another "WWTT"... the sofa jack knife beds…...horrible..they built the beds with different foam on the seat backs.... so when you make it into a bed...half is hard foam, the other is soft...impossible to lay on... the foam needs to be the same so when laid flat it becomes a bed...as is now.... you have to try to stay on the firm part , which is about 24'' wide...
I don't know how I will attack this problem yet,... might have to go to an upholstery shop and have them try to match the foam.... or get new furniture that is useable as a bed...
