Shower doors

[Albertaguy]

I am heading off to Yuma AZ on the 15th of Jan. but in the meantime I have to go and retrieve my Jayco from the snowbanks at the family farm on Monday so that we can pack it for the trip. When I winterized it last Sept I ran into a problem with the shower door enclosure and the doors slipped out of the track at the top. My unit is the 07 BHS325 with the bathroom towards the rear of my 5th. I ran out of time to fix it and I know I should wait until I get to the farm, but am wondering if anyone may have had a similar problem. It seems that the upper track may have lost a screw(or maybe it's me that has a screw loose) but I could not find one lying on the floor or in the tub.

I know I should have gone back when the weather was better but I love to be uncomfortable or maybe it's just a man thing and I was just too lazy.

Any help...... ideas would be appreciated.

Mike
