Truck = heavy
Ice = unpredictable
With those two things put together, yes you're right I lack experience in taking my truck on the ice because I have NEVER done it, nor will I ever. It goes to show you that it doesn't matter if the ice is 8" thick or 22" thick. Its a risk no matter what. And to catch some whitefish, isn't worth the damage to myself or my truck.
This is a forum, which is pretty much based on people's opinions.
In my opinion, its not worth the risk of taking a vehicle onto the lake. You opinion might vary from mine, but that doesn't mean its wrong.
