Question Grey tank on 1964 globe trotter???

Has anyone ever put a grey tank on this model? I've been using the portable tank when no hookup. It would be great to have a grey tank!

For our 62 TW, we used two of the thin tanks that Vintage Trailer makes to go between the floorboards and the belly pan. (The tanks are pretty small, and we thought that one wouldn't give enough capacity.)

So far, this works well. If you try this trick with two tanks, remember to connect the two with *two* pipes: one as close as possible to the bottom edge, and one at the top to let air equalize. Even so, we find that we can empty the tanks better if we use our tongue jack to raise the front end a little bit when draining.

Here it is: Gray Water Tank

I'm curious about the 2nd pipe. I planned on venting both of my tanks a the top. I believe that would completely alleviate the situation. There will be a fitting on top of the tank that will go up through the floor (hidden inside the twin bed frame, next to the fresh water tank), then they will connect and go to the main kitchen stack.

Putting a tank in is fine. Trying to tie that into a single dump valve is the tricky part. You can put an elbow to dump below, but then you have a risk of it hitting something. However, I can't imagine the elbow being that much lower than the lower part of your axle square tube. I'm runing mine down the side, then wrapping it around the new black tank, and the connection is at the back of the trailer at the bumper. The pull handles are in the back of the trailer.

I'm building my tanks from scratch, but if I was only putting in the gray tanks, I'd use the ones from Vintage trailer supply.

Sure: No need for a high connection if both are independently vented. For mine, there was no convenient route to vent the more-forward tank.

Do you have room to install the vent in the high part of the tank? If so, then go about 6" above the tank, then put 2 90 degree el's and run the vent thru the floor and belly pan.

We have gone with a "Nature's Head" composting toilet which did away with the need for a black water holding tank in our 63 Trotter. We also did away with the shower/tub and used that room for the composting toilet. I have installed a 12 gal gray water holding tank in the bottom of the new vanity which also houses our hot-water-on-demand 6 gal water heater. We don't plan on doing a lot of boon docking so we don't need to haul a lot of fresh water around with us.
