Model tank interiors are always difficult to display. This kit provides transparent roofs for turret and hull as optional parts. Much of the internal detail can be seen if they are used, though it is somewhat obscured by the basic hatch shapes molded into the transparencies.
Another approach to displaying the interior is a "maintenance" configuration, where all of the deck the panels and the turret are removed from the tank. While being realistic (unlike a transparent roof), this would reveal the internal detail everywhere except at the front of the hull and in the upper turret.
But the kit isn't designed to support that configuration. In particular, its main fuel tanks and its air intake ducts have been blended into the same parts. This extract from Ustar's CAD data shows one such part. The lower portion of it represents a fuel tank, which would remain in the hull. The upper part is an air inlet duct, which in reality is attached to a removable grating. This kit doesn't allow you to separate the two, therefore you cannot realistically remove those gratings.
The kit provides an engine cover that is separate from the hull roof. This would be useful for a "major maintenance" diorama, where this entire panel is unbolted and removed from the Tiger. But, note that the movable hatch and the fixed rear cover are molded as a single part in this kit. Therefore you cannot have the engine hatch open while still attached to the tank.
