Actually, Winnebago now owns SunnyBrook. You will need to contact Winnebago Industries directly. The General number for Towables is (574) 825-5250. Listen to the menus, they may list SunnyBrook as an option. You likely will need Parts Department.

Contact your local Winnebago (owner of Sunnybrook) retailer or directly here: Contact Winnebago Industries Call Mail or Visit Winnebago

If hydraulic then there is a valve near the motor/storage tank where you turn and then you insert a rod and pump it like you would a hydraulic jack. Electric motor/track slide outs you disconnect the motor and there is a place you manually turn it in.

Obviously yes!! Otherwise the vehicle will try to push your ribcage out through your spine!

You can order one through SunnyBrook . You can also google it and possibly find one without paying for it. Maintainance manuals can be hard to find. http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=9&cad=rja&uact=8&ved=0CEwQFjAI&url=http%3A%2F%2Fwww.sunnybrookrv.com%2F&ei=vOvlVOKuDcHMgwSfoYHwCw&usg=AFQjCNH1VNLS8FGTbclbLnAtCnlpkhLL0g&sig2=_qj4Q8nMxvs20Ed05jz89A&bvm=bv.85970519,d.eXY

You can just replace vent/fan cover.
