Nice caps there, and if it's pegged I believe you should try checking the ground wire

I had asked about my temp gauge because mine doesn't move at all

Then while you are doing that have someone inside the cab and watch the gauge. If the needle goes up when you ground it, then it's probably the sender, if it doesn't move then it could be the gauge.

I agree, the ground wire is the first place I would check.
