Stop in for a cup of coffee

I have a roof and windshield now and bought used wheels and want to go with taller tires. For $400 you can buy a differential lock for the front. Maybe someday but I haven't needed it....yet. I watched a lot of youtube comparing different models and I have had it for a year and have not felt like I wish I would have something else.

Can AM has them with Turbos but where I am unless I am on the road and need speed....why?
