In my search for your manual I kept finding Fleetwood Evolution E3 joined together with Coleman pop up trailers.
Coleman® & Fleetwood
You might also find a manual by signing up here:
Again, this website seems to link Coleman and Fleetwood trailers together:
Coleman Tent Trailer Manuals and Brochures
CanvasCampers - Folding Camping Trailer (Pop Up Folding Camper)
If all else fails, go through your RV front to back, top to bottom writing down each system or appliance you find, noting manufacturer and model #. Then you can Google for the manuals for each one. It won't be the same as a RV owner's manual, but they are very vague when it comes to specifics on wiring diagrams and component exact locations.
