I have been frustrated with the front slide on my Blackstone trailer. It will not slide in or out without using the reset procedure. This spring camping world replaced both motors and railing. Still didn't work. I then replaced the electronic module. Still doesn't work - plus having trouble getting returned phone calls from camping world. What I have just noticed after doing the reset function and running the slide in and out about a dozen times is when the slide is out all distance measurements are equal, but when the slide moves in it both sides do not stop at the same time.
