I would call Adventure and ask them directly. Note that they are talking about FILLING the tank as opposed to having full tanks with the camper floor unsupported.
The issue with filling the fresh water tank is that, depending on the design of the fill system, you can pressurize the tank. 80 psi water pressure can easily "blow up" the tank when the tank becomes full if the venting system is not sufficient to allow the water to escape and the pressure relieved. When on the truck or supported the tanks are much less likely to "bow," at least through the bottom. The Arctic Fox manual warns about this even though you can have full tanks unsupported. At one point there was someone on the forum who had managed to break their AF camper bottom by pressurizing the fresh water tank.
As others have noted this is a pretty big deal and you will want to know the truth.
