I do not know the type of roof lift in your camper. Is it anyhthing like the Rieco Titan system described here? With independent actuators?

page 7 of this PDF deals with their manual crank override:

Or does it use a single lift motor and cables? Can you describe the operating principle?
 
A few pictures of your system might help to extract some more information from the crowd. It was probably not limited to Travelite.
Thanks for the links. The lift system on my camper uses four independent actuators that look exactly like those described in the Rieco-Titan brochure, with the exception of the wall control switch. I called Rieco-Titan who were not able to tell me whether they built the lifts for Travel Lite but I suspect they did at one point. In the truck camper magazine, Travel Lite VP says they partnered with an industry leader, so chances are my lift was manufactured by Rieco-Titan. The flex drive costs less than $10 so I just ordered it. Hopefully, it will work.
