I have a 1995 33 ft Dutchmen Classic with a sticking to inoperable slide out problem. It has gone from an occasional problem to a "I am stuck here until I can fix it" problem. Can any one give me so direction? As I bought the trailer 2nd hand I didn't get many manuals so I don't have much to go on to fix the situation. The slide moves in and out via a hydraulic cylinder and the rack rides on pinion gears. The slide out system isn't a current model Lippert. The slide out has hung up and now is a little tweaked. The top of the slid fits tight but the lower part is still a couple of inches shy of being flush. Any ideas?
