This was earlier this summer about a mile from my house on I-84 outside of Boise, ID. I saw the smoke during my commute home but got off the freeway about a 1/2 before this.
Sounds like the guy had everything he owned in truck and boat and was moving from one state to another. PWC was in the back of the truck too. Truck over heated, luckily, no one was hurt.
Uggghhh...I feel for the guy...Hope insurance kicked in and took care of him
