searching for flat blue boy

My '68 Safari waste drain is only about 8 in off the ground. Having trouble finding a blue boy just for gray water that's lower than that. Any recommendations?

I have a 5 gallon blue boy that can lay flat and the container portion is less than 8" tall (the very top of the hose connection is 8.8"). I like the smaller size because it's easy to manage in and out of the truck when full and is big enough to take the edge off the gray tank with a couple of trips to a dump location without having to move the trailer. If you think the size is ok it might work for your situation. It's available on Amazon:

Moving the blue boy downhill, away from the trailer, and using a longer hose, will take care of the height problem.
I carry a 25' blue hose for this purpose, and use it only for draining gray water.
I use a 10 gallon tote for both of my trailers. About 85 lbs when full is more that I want to pickup and load on the truck.

If you decide to use a longer hose, remember it will not drain well unless the second inlet to the blue boy is open so that it will vent as water flows in.

Look for the 15 gallon "tent camper tote-tank" from Barker. It is less than 8" thick, but otherwise 30" x 33". It is the lowest profile one I have found.

blue tank

Got my 15 gallon 6" high tank from VTS. Full, the tank can weigh 140 lb. To empty it, I stole an idea from this AF site using a 12V cylindrical pump that fits into the tank with a hose connection to an empty 15 gallon tank left in my truck bed. This allows dumping the second tank by tilting it over with a hose going tot sewer dump. OK, I'm too olds and lazy to wrestle with 140 lb.
If it were easy, the PO would have done it.
