Having owned f series big RVs on military tires for almost 15 years, including same as above.I can say the departure angle is definitely not the limiting factor. You got to remember these things are on 40 plus inch tires. Limiting factor is just the overall size in general. Never have come close to even dragging the rear in any situation. What I can say is that I can comfortably sleep a family of four, and even a couple of friends. Anywhere we go regardless of how much snow there is ETC. The setup isn't for Wheeling. But you can definitely get more places anything else this size can.
