plastic taste in drinking water
I have a 2011 trailer so it has pex pipe.After being stored with rv anti freeze in the lines for about 2 yrs I flushed all the lines and bleached the water tank flushed it a few more times before use....

I'd suggest to put some baking soda or peroxide into the system and flush it out thoroughly a couple more times. Make sure all pipes and valves are allowed to flush completely. I doubt you are tasting "plastic" as you describe it from the plumbing because the tank material is food grade polyethylene and PEX is inert to the water. It's more likely that you are tasting the residual antifreeze that was in the system or water from another source that had acquired a taste.
