Thanks for all the answers. The Dometic is 3&9 position. I've been searching installation PDF's of Thetford AQ IV's and V's and I think I'm going to be Okay with your answers doing the swap over without 20 trips to town. Yes my water connections are different and I'll have to cut my water supply line off and make a change in my water supply connection. But, that will give me a chance to add a stop valve for the toilet for easier repairs next time..
Hopefully when I arrive next year I'll have everything on hand and I can have the old toilet out and the new one in, in a relative short time frame.
Thanks Guys...
