Navigator slide out adjustment

[eracer]

Hey, this newbee has a question. I have a 45 foot Nav and the main slideout (drivers side front) does not fit tight to the seal in the upper rear corner when slid out. This gap at the top is about 3/4 inch but fits tight at the bottom. How and where would this adjustment be. This a hydraulic slide.
Hope you can help...

Adjusting one setting may skew another there are also adjustments for tilt so you have to be careful.

I would seek to have this professionally done. You also need to find out why it's out of adjustment as opposed to how it was when you took delivery. There are a number of HR dealers and they should be able to help you. Just find one that you have a high degree of confidence with.
