No idea if you have someone with you when you put the slide out, but if you do... Then it seems to me, adding a remote control would be just adding something else that can break.
When I am concerned that I may hit something when I put the slide out, I open the window, ask my wife to go out and watch the clearance, and push the button. Or vice-versa, she pushes the button and I watch from the outside.
That may or may not be an option for you.
