When it happened to me I was towing a 12,000lb toy hauler. 250 miles from home. Middle of the desert on I-40. 50 miles to the nearest town. Ford sent out a tow truck and towed the truck to the nearest Ford dealer 75 miles the opposite direction from home. I got lucky and a friend drove out that same day and towed our trailer home 250 miles that same day. I've got a spare tube with me since then, but if the tube blowing also damages the turbo, I'd rather have a stronger tube than risk damaging the turbo in the middle of nowhere.
