Believe me, it's legit. That Elk weighed just over 600 lb.s after field dressing. Elk have very long legs so, yes, it would be taller than a stock jeep.
I'll never forget the time that my girlfriend (now wife) were driving through the hills of Eastern Oregon at night in her Fiero. We came around a corner doing about 80 and there was a cow elk standing broadside in the middle of the road. I slammed on the brakes and, when we came to a stop, we were actually looking underneath it's belly. I wouldn't be here today if we had hit it.
