Hello all, I recently purchased a 509 and put an outlet tester into each AC 3 prong outlet. The tester indicated a bad ground for each outlet, meaning the ground is fine at each individual outlet; however, somewhere the main ground is not making clear contact or is disrupted. Any advice on how to fix this issue will be very helpful.

Are you plugged into shore power when doing this test? NEC only allows a single ground/neutral bond, and that happens at the power source. 

Ground and neutral should NOT be bonded in the camper. If neutral and ground aren't bonded when the camper is plugged in, there's an issue with whatever you're plugging into, or possibly the power cord.

That sometimes causes issues when using generators - they typically don't have a ground/neutral bond, but should when used with an RV. That can cause problems with GFCI outlets. There are bonding adapters which take care of that.

Mike - Elaborate on the generator.  I use a Honda EU2000 and can either plug the entire Retro or just the AC into it.  Should I be using a bonding adapter when plugging the entire Retro in?  New one on me.   Tom

If you don't have issues with the GFCI, don't worry about it.

For generator, my surge protector kept erroring out with a faulty ground- helpful folks pointed out to use something like https://www.walmart.com/ip/Southwire-Company-LLC-44400-Surge-Guard-Generator-Neutral/906720166 - essentially I think what mikes is referring to. You can make one cheaper, but Walmart was convenient 🙂  But if not plugged into generator, then not sure.
