Toilet seats super loose in our '08 Dynasty Renaissance IV

Mine is accessed by pulling up on the tile top/cover behind the seat to remove it... Velcro holds it on. You may have to remove the control board to get to the nuts... wires are long enough to move it.

On ours the top of the toilet seat hinge flips up and the bolt is right inside.

What kind of toilet do you have? If it is the Tecma macerator toilet, the only way to tighten the nuts on the two bolts is to reach behind the toilet. Depending on how its installed, you may have to remove the bolts holding the toilet to the floor, pull the toilet forward to gain access. The original nuts used on the Tecma are strange looking wing-type nuts that are hard to tighten with most common tools. I replaced my seat recently and used 7/16" hex nuts so I could tighten them with a 7/16" socket.

In our 1/2 bath, I had to remove the toilet to get to the seat nuts/bolts. That also meant getting a new closet flange gasket.

A toilet control board? Life is complicated. :)

When you do remove it for access, ground yourself if you touch anything on the control board. Static is very bad for any electronics especially containing IC chips. A ground strap is a good idea.

1. Some toilets you do have to pull to tighten the Seat bolts
2. Usually, if you lift up the seat to put pressure on the underside nut, you can then turn the slot/phillips screw tighter.
3. There is one toilet (not sure of the model) where you have to tighten on the bottom side nut, they have no screwdriver type screw on top.
4. WHY would you go to the Factory for this type problem???? Go to a RV Service center. Doug
