I re-read your posting about being told to remove the rodent traps as they may be interfering with the slide issues. So I guess this means RF interference perhaps? You either have Rapidcamp or the Firefly multiplex system on your coach probably Firefly). I read that the Rapid camp may have had issues and it may have been the reason Thor went with the Firefly system in newer coaches. If your 2019 has the Firefly control for slides maybe their tech support folks can help you troubleshoot their system or at least advise you what other wireless systems may cause interference.
