We have Bindel Bidets. All 3 toilets in the house have them, and I installed one in the camper. We've had both a Thetford and a Dometic 310 (we currently have the 310) and the same Bidet switched from one to the other just fine. Ours is the simple one ... remove the seat with the 2 plastic bolts, slide the bidet in place, place the seat on top of the bidet, and rebolt it down.
Water connection was easy, but I improvised a little by add a cut-off that matched the supplied water line that came with the bidet (like in a house connection). We've been toilet paper free now.
As stated above, we also installed all of ours Pre-Covid hysteria. When everyone was going insane hoarding TP, we were laughing at the insanity. In the last 5 years, I think we have purchased, maybe ... 10 rolls of TP, mostly used for blowing noses or picking up after the dog when they have accidents.
Our septic tank at home is better off, and our black tank in the camper is much cleaner without all that paper clinging to everything. (yes, use a clear section of sewer hose on your stinky slinky so you can see what's actually coming out).
The only down side of the non-heated, non-blow drying bidets is the .... "uhh-la-la" you get in the Winter!
