Ah, a practice near and dear to my heart. I'm good at getting 8N's stuck, and have lots of practice at it. :-) Don't try pulling the front suspension. It will come off. No, I haven't (quite) managed to yank mine off, but I did observe one can induce a fascinating amount of distortion in the front axle without impressing the thoroughly stuck rear tires in the slightest. I like pulling from the rear axles. They're pretty strong. So I'd rig up a cradle chain that wrapped around from one axle to the other, with the hoop of chain extending out front. And connect my towing chain to that hoop. Then all the towing force is applied to the strong axles that can take this kind of force. I would use chains. Not cables, not snatch straps, not ropes. Straps and such are nice in certain applications. But the thing that makes them nice can also make them nasty and wrong. They work by stretching and applying gradual tension. That's good for gentle easing out things that aren't too stuck, or for catching things already moving. But unpleasantly inclined to rip off axles by continuous tension when tugging on stuck things. Chains on the other hand do not stretch. So once you've taken up the slack, things must move, or break. Usually they move. I like that. It also means once the object moves, there is no more tension. You can see very clearly if tension is causing things to move with a chain. It's the difference between gradually leaning on a wrench harder and harder, or smacking it with a hammer. The former tends to round off heads, while the latter breaks a stuck bolt free. Chains also do not kill when snapped, like a cable or rope will.
