I replaced my toilet with the Dometic 310 with hand sprayer. I didn't buy the Dometic 320 as it would not have fit in the tight confines of the toilet room. Checked out the dimensions online and the 320 extends to the rear deeper than the 310. One new piece of hardware I came across at Home Depot was a flexible reinforced water line that ran from the old PEX piping to the toilet and had a Sharksbite type valve on the end where I could shut the toilet off in the future if required. I ran into the same issue with alignment of the toilet inlet vs the PEX plumbing. Fortunately with a little looping of the flexible water line it all came together.
