AFAIK, comparing a TT to a TC wrt holding tanks, doesn't matter. TC's are the only rv with an unsupported floor when not in the bed.
For the AF, they just need more support of the holding tanks instead of telling customers they have a special way to fill their tanks. Otherwise, I wonder what happens to the Black/Grey if they are "over filled".
This issue really doesn't have anything to do with the support of the holding tank. What they are saying is that if you pressurize the tank using your water fill ( I suppose you could get up to 80+ psi depending on your water pressure) you will bulge the tank. If you subject any manufactures tanks to that kind of pressure you will probably get the same result.
The fault, if any, ls that the tank vent is too small to adequately release high pressure on the tank. I don't have a know how well others vent their tanks. Anybody want to try and report back? :)
