Question on cable adjustment, please.

[maryo1944]

We have a '94 Destiny Rio Grande.  It's getting harder to raise and it doesn't go all the way up. The cable adjustment pulleys are at the last adjustment and it's still an inch and a half short on height. How can we adjust the main drive train area?  We have the camper manual and the instructions aren't very clear. Any help would be appreciated. Thanks
