Are you sure the tank valve is open?

Another option is to get a Flush King with a gate valve and try to force the clog out from the bottom with a garden hose. From what you have described I would be surprised to find it still frozen.

I vote for the Flush King Valterra F02-4350 Reverse RV Flush Valve: Automotive

or the Camco unit

to help out. By back filling a little, then draining and back filing over again you should be able to wash the gunk out.

Here is a video on how to use it.

Maybe the warmer weather forecast this coming week for the eastern half of the US will help if you are in that area.

How about turning off the water to the toilet, then flushing it with very hot water poured down the toilet? Sounds like you need to thaw out a block of poo.

He did.
He also said he shut off the water and ran a snake down through the tolit and was 'certain' he went through the valve. If he did in fact get a snake out through the valve that would mean the block is somewhere after that.

I don't know the specifics on how much pipe may be between the valve and where he hooks the sewer hose on so it's tough to keep guessing as to where the problem lies without knowing more details.

Frozen black tank

Obtain a elbow with a flush hose hookup, and attach it to the drain, then reattach the hose. Run a high pressure steam in from the bottom to thaw the valve. Although you may have the valve rod pulled the actual gate may still be slid across the opening. If you were pulling on the rod while the gate was stuck to the frozen contents it could have pulled free. See if the valve Rod seems loose or if it is actually moving the gate.

I wonder if that calcium products used to melt ice dams on roofs would help or hinder.

A blast plunger will likely not work as the black tank is open vented to the roof of the camper.
