Agreed... I guess I hadn't considered the tank being above the floor... Is that a common occurrence in modern rvs and travel trailers?
In the RVs I've owned, fully 100% have had the fresh water tank mounted on/above the floor. I'm not sure a sample size of one RV is statistically significant, though.
I think it's reasonably common in general, perhaps more so in winterized/semi-winterized RVs as having the tank and plumbing "inside" is an easy and cost-effective way to keep it from freezing. (The grey and black water tanks are trickier, as they don't work above the floor level for rather obvious drainage reasons and so need to be in some sort of a heated bay.)
