Just bouht a new A126 hard side pop up. It came with an addendum card on opening and closing the camper, but the "owners manual" was for the Flagstaff line of tent campers.
Very general, mostly useless.
You'll find asking and searching here is tons better!
I will add that the individual manuals for the appliances and other components are handy to have, and as Herk said are usually on the appliance manufatturers website for that appliance.
