What percent of the time do you leave your TC on your truck?

On our fine diesel truck 100% from May thru October. Then it's off the truck and the 5th wheel hitch is on for our 5th wheel for the months only of (during Nov - April). Best of both halves of the year! Spend 2-1/2 months (2nd week of Jan - late Mar) at our winter snowbirding CG about 100 miles south into Florida as is needed for my disalbed wife and also have family members down there in Florida we visit.
