As suggested, I tested the slides and they moved immediately. I also found no sign of hydraulics to the slides, so I guess they are electric, not hydraulic.
I'm still hunting down documentation, though. Only when it became a deal breaker did the Camping World sellers of the used fifth wheeler provide the chairs and the documentation. After I got it home I found the documentation was incomplete and much of it did not match the equipment.
I contacted Forest River through their web site asking for documentation that matched the VIN. No response in a week.
I found some generic Forest River info at Forest River Manuals
, but I need some info that fits my RV.
Do you have any ideas where I can find basic information about the camper itself, like electrical, propane sensor, winterizing and so on?
