Nice write up Batman! I have the same model as you. I just did not catch your post until now. I have had mine for almost a year. I have not done as much off-roading as I would like, but it sure does help! It gives you awesome grip on rain-slicked streets, but you will want to practice in the snow and get used to how it works.
Last year I was in some combo snow\slush\ice and if the front end was building up too much snow, even in 4wd, the rear end wanted to push the truck sideways! A rather interesting sensation
! So if you drive in the snow, find some safe area to practice in. I ended up shoveling in a load of snow to get some more weight in the back, that helped a whole bunch. By the way, your truck will now do some awesome donuts!
Have fun and be safe.
