what do you do if the truck needs to be towed?

Thanks for the replies, guys.
Some of the reasons for the question are that yeah, our TC already puts us at 12.5 feet, so height is an issue. We carry a Lance 1181 so we are both long AND heavy.
DH retired from Ford so he immediately bought the tools and sensor and replaced it himself. We'll be carrying a spare, I am sure although apparently the new sensors are better.

I like the idea of saying we have a 26 ft "class C size"vehicle.
