Kurt, two different questions. No you don’t need to raise the nose, it is sloped to get the most water out of the tank when it is level. Your question was where is all of my water. Some of it is still in the tank if you did not raise the front to get it out when you were measuring. So, you have 64 gallons of capacity, you had water in your water heater, lines and since you didn’t raise the front, I would guess you still had water in the tank.

If you do a lot of boondocking, I recommend the SeaLevel Gages so you have accurate tank measurements and a water bladder and pump from harbor freight to augment your water supply. In another thread they talked about the 40 gallon bladder. And while you have the coroplast dropped, switch to Valterra sold wire dump valves. Also, look at the ARP Fridge Defender. We live in the mountains and are going up steep grades all the time. Hope this helps.
