Michael, during my off time (two weeks), to be exact, June 27th, I took the motor home to the dealer and got with their mechanic. The slide out was not the problem and it was doing just what it was supposed to do which was nothing when it did not have enough power. Let me explain. This is the first motor home that my wife and I have had that has a slide out. Yes, we've had a fifth wheel with slides before and the procedure there would be to run the generator or be hooked into shore power and activate the slide (best way), or the slide would just work using the batteries coach batteries. Evidently with the motorhome, the slide out is powered ONLY by the chasis battery or from the engine power and not the generator or the coach batteries as the fifth wheel was.
So, of course the slide out is not going to work when the chasis battery is shot. The RV mechanic also told me that it was best to be running the engine when you activate the slide. I am not sure if I knew that before and when you receive a turnover while buying something you are told so many things in such a short time, its very possible we were told this information.
So, since we had an appointment to get the slide out checked at the dealer already on the calendar, (before I had the new battery installed), I didn't bother to check the slide after having the new battery installed for the chasis. If I had, I would have probably seen that it worked. The mechanic did say that there has been previous problems with the type of slide out module that my motor home had installed, and he did replace it with a newer one. Hopefully, a better one. Of course he did charge me for that item and labor.
I'm now accepting your answer since the problem is now solved.
