I HAVE A TRIPLE SILED PROWLER 5TH WHEEL, ONE OF THE SLIDES WILL ONLY MOVE 2 TO 3 INCHES WHEN I TRY TO CLOSE THE SLIDE OUT. THE OTHER TWO SLIDEOUTS WORK GREAT. ANYONE GOT ANY IDEAS ABOUT WHERE TO START TO REPAIR THE PROBLEM. I NEED TO SLIDE IN THE SLIDE OUT SO WE CAN MONE THE 5TH WHEEL. WE KEEP IT AT THE LAKE 60 MILES TO TOWN.
