Just Remember...It's the GEAR BOX...
The motor seems heavy duty enough to move the slide. The problem has always been the gear box. Maybe put the one that is being used in the front slide, since no one seems to have had problems with those.
Now I see that your link shows the motor and gearbox combination. My unit had a motor, then about a 3" flexible "old style speedometer cable" shaft, then the gear box.
I suppose that the combination unit would work. Might want to find one that has the ability to run the slide in and out if the motor burns up. Socket on the end or the flexible coupling that we have now.
R25076 No. 1308 43064 is the number that is on the gear box of the one that failed on my 25DS.
The unit is all tied together in one piece so if the gears match I would suppose that any one would work. You might think that Forest River would be making the suggestion for all future repairs...You would think...
