Toilet issues

[Explorer]

My wife was a hard sell. We do not put paper down the toilet.
We use less water, gauges are more accurate, no problems

If it didn't pass through us it doesn't go down the loo.

Tank design on modern campers is shallow. This does not allow for good pressure behind the flow. The old Winnebago I have is great, with half the tank very deep.
Try blasting water back into the tank with one of the Rhino elbows with a hose connection and ball valve. I have put another add on Valtera valve below that to build up water and pressure on tough blockages. Be careful if you do that.
