I was thinking I needed slide out parts but finally figured out part of the problem was a manual 50 amp 12 V breaker that was bad. Once I got that squared away problem #2 was a hydraulic release valve that was opened for manually closing the slide , once I found that and closed it everything worked good. I learned the hard way that youtubers suck at camper problems , I followed them down a rabbit hole and was convinced I had serious issues but I learned a lot just by tinkering with it. I thought I'd be dumping a bunch of money and time into it but everything is working so I'm happy to say it was a false alarm.

Just bought it and the previous owner wasn't much at fixing things so it will take a little time to get the bugs out of it.
