The hab I built is ~23' long at the top, resulting in about 7' of overhang from the rear of the aft tire and 12' from the rear axles
actual pivot point.
It's definitely a double-edged sword: I
LOVE the space but I am very cautious when maneuvering. It might not be everyone's cup of tea, but works for me. If you're comfortable driving a rig this size, it shouldn't be too much of an adjustment and I haven't found it overly limiting. In my use case, this vehicle is taking the place of a coach, so in that respect it's still more maneuverable than a 35-40' rig.
Full build thread is in my sig.
