Um... I just looked up the installation instructions for the American Standard Princeton. Near as I can tell, it doesn't say to use a mortar bed, but it doesn't say NOT to...
Also says to butt the cement board to the apron - not to extend it under the apron, like you have planned.
note: I couldn't attach it, too big. Here's a link to the download:

I have a couple of pieces of melamine and/or MDF board that is 1/8" and 1/4" thick. They seem to be a perfect fit for raising and leveling the floor to set the tub apron on. Is there any drawback to using it or should I find a different material?
Yes. Either of those will fall apart if it ever gets wet, or even damp. I'd want something reasonably rot-proof, like exterior ply or cedar or even just a regular doug fir 2x4' cut down... I think floor leveler was the best plan I've heard.
Almost anything is better than mdf.
Don't you think the floor leveler will break into pieces being only 1/8" to 1/4" with the minor flexing of the sub-floor?
I agree with the "no mdf".
I would think so!
I wonder why the don't want you using a mortor bed. Could it be that they are building such crappy tubs that they have high warranty claims so they want the option of easy removal?
I just installed an American Standard Jacuzzi tub and I've already had two warranty repairs in less than 6 months.
