Question:

I have a 2010 Damon Astoria 3772 Motorhome. The driver side front slideout motor is getting really slow and probably needs replacing. I have narrowed it down to a couple of Lippert motors but cannot confirm which one. Can you determine which replacement motor that I need? Thank you!

Before replacing the motor, you'll want to make sure its receiving a full 12V and it's properly grounded. Those motors work hard, and if they're not getting full power because of a supply or ground power, they aren't going to work right.

The # LC386322 replacement motor assembly replaces the Kwikee assembly motor numbers 387738 and 386322. The other motor you'd looked at, part # LC138449 replaces a Klauber D-300 Slide-Out Motor.

For a replacement, the best way to specify the correct replacement motor is to get the manufacturer and part number off the existing motor. Unlike a typical passenger vehicle, knowing the year, make and model of a motorhome or RV won't help you find replacement chassis parts as they can vary greatly within the model year. If you can reply with that information, I'd be happy to make a recommendation.

I've provided links to product description videos for both motors you'd looked at.
