The slide on our 2007 Pace Arrow 36D was becoming intermittent when I would try to slide it out or in on different occasions. It seemed to be worse if it had set for a while. It would hesitate to start the slide moving and at times even kick the relay out and I would need to wait a few minutes to try again, usually it would eventually start and retract or extend the slide but was definitely time to replace. After checking all the voltage and wiring to the motor and finding no problems there I decided it must be the motor. This motor is a direct replacement and bolted right in place where the original came out. This motor appears to be slightly heavier and has a larger gearbox even thought the bolt pattern is the same and it fits in the same bracket. It moves the slide easier than the original ever did and locks in place when retracted tighter than the original. Time will tell if it lasts as long but so far I am well pleased with the fit and how well it worked. Since one of these costs 5-10 times more from the factory or trailer supplies, I can replace it several times and be money ahead for years to come.

The housing split on our old slide motor, so we got this as a replacement, with a pack of roll pins. It fit perfectly, and works beautifully, thank you!!

Works great, just needed to add a roll pin to work with my bedroom slide. Much more affordable than one from a RV dealer.

Gear motor was not an exact replacement as specified. I was able to grind off some metal to make it work. Functioned fine after the alteration.

I liked the gear box was a little bigger, but the motor was smaller. Seems to have power to move it.
