Automatic battery disconnect???

I just went to pick up my 5th wheel from the dealership as it's been there for a couple of weeks for warranty work. When I backed up to it to hook up, the landing gear needed to go up a few inches to line up with the hitch. No problem, I hit the ext/ret button and nothing. No movement, no noise, nothing. The service person comes and and plugs the plug into my truck and magically it works. She asked if I had a battery disconnect and to my knowledge I don't but after plugging in the 7 prong RV plug to the truck once, now even disconnected from the truck everything works as expected including the landing gear. What am I missing? Is it possible there is an automatic battery disconnect or something along those lines that if it's sitting unused for a couple of weeks that it disconnects to save the battery??? This is on a 2014 Heartland Sundance XLT.

That's a stumper. Most factory disconnects will at least leave the landing gear hot. I know mine does. Not knowing how long your drive home was, I seriously doubt that you got a 2/3 charge just from the truck, unless it was cross-country. If you do have a battery issue, I'd have a serious talk with the dealer as they should either disconnect the batteries when it's not in the shop. I'd also wonder why the solar isn't keeping the batteries up more. Again, I seriously doubt that the solar system would be tied into a battery disconnect. Personally, I'd put the batteries on a trickle charger for 3-4 days, then have them load tested. I wonder if there's an auto-reset relay in line on the landing gear wiring.
