The slide motor for the rear slide can be accessed through the rear basement storage door. It is above and to the curb side. The Main Slide has an access cover under the street side wing that must be removed to access the motor. To me it looked like the weight of the electric motor levered out of the gear box broke the housing due to the sharp impact from traveling on less than smooth roads. To prevent this in the future, I installed a brace to support the weight of the electric motor. I did not take any pictures of the support though. I was in a hurry to get it repaired and get back out camping.
