Anyone know how tall this truck is?

There's a phone number in the listing. Seems like making a call could answer all of your questions.

12 inches to the foot my guess.

 

What if he hits a pothole and bounces?

 

As mentioned, call the dealer, ask them to send you a picture of the height warning sticker on the front of the box.

 

Box is 103 high, 295 tires are 40 inches, add a 3 inch gap between tire and frame plus a little "cowboy arithmetic" - 12.5 feet on the low side, 13 feet on the high side.

 

With that standard box height Most are around 12’-9” on 11r 22,5’s. Both of mine are.

 

The sticker on the box for the truck in the picture says Truck Height 13'0"

Save the picture to your computer then open it and zoom in.
