Always surprised at the timing of other people's posts in this forum. We are looking at making the same upgrade for the same reason. I believe there was a "silent" recall (good will replacement) on Dometic 300 for leaking seals improperly installed at the factory where they sent out 310s as replacements so I'm assuming that they will fit. Ours is out of warranty and didn't show any signs until about a month ago.
