I'll look into adding a sprayer to my 2012 Thor Tuscany's toilet. My previous Monaco Monarch had one and I really liked it.
When you spoke the downside of "sharing water pressure to the wand with the flush," it reminded me of this trick: if you push the thumb valve on the wand BEFORE you step on the pedal for the flush, it seemed to direct a little more pressure to the wand. You might give this a try.
