Thanks for your time and the suggestions, we took on a box of gloves and sanitizer today after I mentioned your inputs.
Thanks for the tips on glove usage and not moving from that spot without removing them. Common sense but having it reinforced makes it stick.
I'm going to continue playing with the pressure regulator to make a decision on whether to use it. Thanks for the suggestion on just full timing the fresh tank and pump.
I did look at the cam system for sewer and it's in my box of things to consider if the wrench doesn't work out. Not only is it easier but it looks to be fool proof.
Our TT has 2 gray tanks, one of which doesn't share the black tank output. A future project is to see if making the 2 dump outputs common so I don't have to spend as much time switching them or deploy as much hose into a 'Y' which I don't have. Something to fuss with until I get a better solution.
Thanks again
