The dinning room slide on our 2500TS does the same,,, bottom out first,,, top in first,,,
I believe that is because the motor in on the bottom !!! I have been thinking about putting a very small amount of pressure on the top as it goes out ??? We used to do that with our old TT with Super Slide,,, we would help it in & out !!! I have however never seen our Dinning room slide move out when traveling !!!
