<3 Mawloc!

While it can be a jerky move, I do think there is some logic to the idea of a Mawloc (or a Trygon even if the rule doesn't support it) creating tunnels underneath a super heavy vehicle and causing it to crash into a sinkhole. You are allowed to move the super heavy away from the blast if there is room, so it wouldn't be an instant kill if there was decent spacing but then again, when I think of Apocalypse games I envision almost a normal sized game with a few huge units bumping the points up much higher and not the solid walls of steel that you'll occasionally see in pictures of games at events.

Every apocalypse game I have seen has been a very crowded affair for the imperial faction. Something as bulky as a superheavy tank or titan would literally have nowhere to go in the vast majority of such games.

Well, whenever a super heavy/gargant would be slain outright it tends to suffer D3 wounds/structure points instead, so as a house rule it's not too bad. I imagine something that big falling would SUFFER, but would still survive.
