New Toilet and Holding Tank

Regarding my '71 Carravanner (still working on it). As you know, this year model does not have a gray tank. As I want to change the interior layout, I will need a different holding tank set-up.
My thoughts are to use the existing black tank as a gray tank, and build a new, more vertical black tank, and use one of the Thetford Atlantis toilets. They have a built-in macerator/pump, so can pump uphill to the inlet of a tank.
Have installed several of these in yachts, and they have proven to be a dependable, and clean running unit. They only need less than a qt. per flush, of water.
After spending a whole year in a SOB, the issues of a "bottom dump" type unit, with a flat shallow tank, I find to be a pain in the ,,,, the "solids" never really dump out all that well, not to mention having to use special (read weak) toilet paper.
Any issues of power/water are not a hinderance to me. A tank that is around 2ft. long, by 18in. tall, by 14in. front to back, will hold better than 22 gal., and is more than I need.
Does anyone have any experience in this type of set-up?
