Best you can most likely do is find the make and ton of the rig itself and find a generic manual for it. Then find spacific manuals for each serviceable item IE; refer, stove, furnace.
Hi ebm11862 and welcome to the RVUSA Forum. I found several references to Cikira RV's in my Google search. If you asked nice and offered to pay for copying and postage maybe one of them would make you a copy. Good luck.
