Robert, Keystone uses Lippert slides in their trailers and manuals for them are available for them on Lippert's web page. Prowler is made by Fleetwood, and I don't know who makes their slide out mechanisms. You might want to try a forum that contains Prowler owners. Travel safely, Hank
If your slide-out is a Lippert HERE
is a link for their manuals. Hope this helps.
