Thanks for the insight, helpful to know that TCs are exempt from any kind of codes, and that this isn’t that unusual. It looks like I’ll just be adding a 30 grey tank and replumbing the grey fixtures into it.
The blue tote is a great idea, and I will additionally bring one or two in the trailer with me for extra capacity when needed (We’re not the most conservative with water, coming from a toy hauler with a large capacity). But I must add a grey tank for the convenience, and as I tow various trailers behind the tc, would be inconvenient to have to wheel it out of the trailers whenever I needed to use a fixture when on the road, but they are excellent for boondocking.
Ours is just to get by a couple of days, such as when visiting and you don't want to dump grey water in their driveway.
Here are two photos how ours is. You will want to keep the receiver clear for towing--will need extension too. The tank has to be hung up tight for not bouncing. It is heavy when near full. Also secure against fore and aft swinging. I used an old washer hose as shown there.
You could add a 90 turn and a valve to the tank "top" now at the bottom, but it would be in danger of getting knocked off hanging so low.
