*cough* *cough* bullshit *cough* *cough*...

It may feel like 70 degrees, but it's not... anything over 40 degree side-angle, and you've got one side of wheels off the ground, heading for the other side... How do I know? 'Cause at +/- 39 degrees, I had one side of the truck in the air; both wheels off the ground. If I didn't have a locker, I would have kept right on going, 'cause I wouldn't have been able to keep driving straight. It was at slow speed, so there was no denying what angle the truck was in. 70 degrees, and you'll be crawling out your driver's side window, wishing you had built a cage, afterall...

As for the front/rear clearance, sure, 70 degrees, even 90 degrees are possible, for a 2' tall object... Anything taller, and you can forgetta' bout it... Not unless you've figure out someway to make the tires climb up a verticle face... Not gonna' happen.
