Best size underfloor water tank?

Now that we have the shell off and we are doing a full resto on the frame it's time to add that new below the frame water tank as well as a spare tire rack.
Any suggestions on what size tank is best and where is the best location.
My guess for the water tank is just forward of the axle and a 9inch deep tank would be max. Regarding the spare tire rack, I see that there are a number of options. Anything to stay clear of or suggestions?

The water tank in our 1970 Overlander is an Inca T1237 with 33 gallon capacity. It rides just forward of the front axle and extends no lower than the axle tube. is still in existance, but their website appears to be down tonight

My frame is close to the same progress as yours just painted and on the flipping yoke axle not installed yet! Next is floor belly pan and axle! Then we can start putting it back together. Your doing great!
Gotta get busy! Have a great day! Now where did I put those revits?

Several years ago. we had our tanks custom made by All-Rite Holding Tanks. We sent them the dimensions of the inside openings of our frame minus 1/2" to maximize the tank capacity without having it drop below the belly pan. We ended up with two gray tanks and a black tank - the black tank sits on the floor with the low-boy toilet on top of it.

The tank install and complete restoration can be seen in our "It's a Girl!!!" Thread. Your dimensions will vary and I know the prices have changed since 2007.
