the hull points are by far the easiest of the mega battle rules to deal with. going over the lists in the back of the book most vehicles have 3, super tough things like war wagons, land raiders, and monoliths have 4 and squishy light things like land speeders, war walkers, sentinels, and various buggy type vehicles have 2. so its very easy to just give the odd pattern land raiders and rhinos the same as the ones in the book.
as for super heavies thats an odd situation you don't want them easily killed but useing the old glanceing rolls in the new system is a bit weird..hopefuly GW will get a errata up for apoc soon. but if not I would be willing to consider giveing super heavies 3 hull points, with a special rule stating when they loose there hull points are reduced to zero they loose one structure point, and whenever they loose a structure point they recover all lost hull points. so they can be poked to death with glances but it will take alot of them.
