One of the biggest issues is trying to pull weight with the drawbar too high, it needs to be down as low as it can be. And they weren't really made for slopes.
Like I mentioned earlier, I have hundreds of hours on these things, I've popped the nose off the ground a few times (not on purpose), it's almost "too easy" to do.
