Trail lite BPlus winterization woes!!!!

I recently purchased a Trail Lite BPlus 2004 motor home. I did not get a r-vision motor home manual with it and thanks to the kind souls on this forum I was able to download a manual, but probably not for my year? For example, it says to winterize, you can drain the system and fresh water tank by" going to low point drains located under (?) the motor home They will be labeled to show correct position(handles turn one way to open, the other way to close"
There are NO valves under this motor home! Under one cabinet by sink is labeled "low point drain" and another on the dinette seat that houses the fiberglass fresh water tank. In these corners are pop up valves with key ring pulls and the one by the fresh water tank and pump is another small turn valve attached to what looks like a outlet from tank. I have opened all valves and it still appears that the water tank contains about 6" of water. When I hold flash lite up to opaque tank, it looks like a undulating shadow(I assume to be liquid water) moving when I rock the motor home. I am in upstate NY(Ticonderoga) and I have been keeping a Polonis ceramic heater on since freezing weather hit. Am I missing something with these drains??? I did open all sink handles and even used air on the city water inlet but I am bewildered on why the fresh water tank is not draining. Any help will be greatly appreciated!

    Still frozen even with the ceramic heater? WHOA! Any way to keep things slowly circulating?

    No, you've got it about right. We had a TL B+ too. The drains are inside, where you found them. And the tank does not drain completely. I used to pick up and prop up the other end of the tank to drain it better. Then whatever is left in there can freeze and won't hurt anything.

    Another thing I remember is that it took FOREVER to drain the tank through that little valve.

    I hope you drained the water heater from the outside as well?

    Run the pump dry, too.
    And/or unscrew its pipes and drain it.

    And don't forget the outside shower. And the city water inlet.

    I think I eventually added a 3 way valve by the pump so I could use pink antifreeze. Another way to do the same is to buy a winterizing hand pump that attaches to the city water fill. Whatever you do, don't put it in the fresh water tank because as you see, the tank doesn't drain, so you'll never get it out.

    Here is a nice Camco document on winterizing

    Is the fresh water tank drain in the lowest point on the tank? If not re-position the MH so that it is. If necessary use wood blocks under the wheels, or park it on a slight incline. Generally there will always be a small amount of water left behind in the tank, which poses no threat when frozen. There should be a tank drain valve (right on the fresh tank), and also one or more low point drain valves. Have you run pink anti freeze through all the water lines, or at least have blown them all out with air pressure?
