I have an Aussie (actually, two Aussies) in my Jeep. Once you learn to drive with them on the street, they aren't "that" bad UNTIL the weather gets hot and the tires get sticky. You WILL have violent unloading, lurching, etc.
The front one is only an issue on pavement when doing full lock u-turns.
On the dirt, the front end will push a little and decrease your turning radius. In my opinion, that will make you have to do some 33 point turns on the trail.
Just making you aware based on practical experience.
Now, this is the part that you aren't going to want to hear: You may want to bring whatever tools are necessary to remove that stinger. You are wheelin' a Prevost Bus on trails that were build for a 59"x80" square box. Making it even longer is going to be really frustrating.
BTW: Here is the entrance to Leaning Tree:
