Many folks get some amazing things accomplished with the BX machines. But, I agree with the other posters that they are a bit on the small side. Have you looked at the L3400 and L4400 ? They are economy versions of the L. Less bells,etc.
Since you have some steep slopes, you should make dern sure that the rear wheels can be adjusted to widen the stance. Some of the lower prices models have a fixed welded wheel. You will want to have the tires moved out to the widest they go and have them filled. CaCl2 with inner tubes or the more expensive "beet juice". Or the mid price windshield washer fluid with no tube.
On trail length, you can pretty easily get a mile trail. Depends on the lay of the land, but follow the perimeter and the high ridges then make a low pass.
