I own two 800XCs (the predecessor).
ones a 22 and the other is a 23.
Despite a few issues I have 3000 miles on one and 2700 miles on the other.
I have never had to walk home.
I use them for work around the house including skidding relatively small logs 12-18 inch butts and up to 30' in length and my yard consists of what many people would consider a recreational hill climb.
There are spots in my backyard that hit a true 45 degree angle and the machines handle it readily.
I do regular maintenance (maybe a bit OCD) because I rely on these machines to bring me home from the woods year round and I run tracks on them as well in deep snow.
