. So I'm going to fill in my preferences and why and others can throw their 2 bob worth!
There is an opinion that if yer tires aren't rubbing they ain't big enough. I have a slightly different view on this which goes like this: If your tires aren't rubbing you've got too much lift!
Body and chassis lifts for mine are a product of wheelbase. Got a long wheel base you need height, swb not so necessary.
The critical angle is what I call the interference angle, I've heard it called sommat else but can't for the life of me remember what it was. Anyway its the angle that defines how big a bump you can climb over without bellying and it's a bit like entry and exit angles. Not so important for Swamp Chargers but very important for Rock Crawlers
Now me, the critical things that I keep in mind is CoG, Good old centre of gravity and tipping moment. I look after the former by not lifting anything more than I have too, so my Paj is pretty much standard except for a slight torsion bar wind, even with 33s on and I look after the latter by keeping my front antiswaybar in place and look after articulation by taking off the rear one. That stops the heaviest bit, the motor, from leaning over too far. That gives me lots of stability around the sides of hills even with a bloody great tin can attached to the top.
And I can get away with it because it's a Short wheel base and with 33s on, it gives me a reasonably respectable interference angle for climbing over banks and drop-offs...... But of course I don't go Rock crawling in the thing.
and if I did she'd have hydraulic or air controlled suspension on the front at least and stretched trailing arms with coilovers on the back So in summary, that's why the Paj has no bodylift, only a little suspension lift (so I can feel the tires occasionally) and no rear swaybar.... and of course chassis rails shortened as much as possible to maximise entry and exit angles.
