Sofa size for a 2510 Tip out
 

I own a 2510 with the tip out which has a leather like sofa that folds out with an air mattress. I have it stored a few hundred miles away so I can get a measurement I need.

I would like to replace this sofa with a Fulton type sofa with a real mattress but I need the dimension of the opening which is the width

any help would be appreciated

raamw, I have a 27' er with the tip out. Just measured the base of the frame at 70" with about 1" on either side. My frame sits on two 2 X 4s stacked on each side. The whole opening is about 72". Sound about right? Hope this helps.

Just a thought. Save the original couch for resale purposes.
