I do keep track.
2011 - 1,275 miles - 12 nights - mostly one trip to northern Arkansas from Dallas
2012 - 3,671 miles - 57 nights - all in Texas - two trips Dallas area to Houston area
2013 - 3,089 miles - 59 nights - all in Texas - one trip to Corpus Christi area from Dallas
2014 - 6,586 miles - 307 nights - two trips to west Texas / New Mexico
2015 - 9,253 miles - 365 nights - West Texas to Dallas to Key West to Connecticut - to Dallas
2016 - 810 miles - 59 nights - Central Texas
My first trailer was from Sep 2011 to Nov 2013 - 7,663.5 miles
My current trailer from Nov 2013 - 17,022.5 miles (replaced original ST tires after 9,000 miles with higher load range tires)
We have camped at least one night in 29 different states with the current trailer.
My current TV - 2012 Ram 2500 - has towed both for 21,469.7 miles - yet the truck has 55,000 miles.
My unscientific guess, not knowing anything about their lifestyle, is that 160,000 miles on the truck means between 80-100,000 miles of actual towing.
Seattle to Hartford will be about 3,000 miles towing without side trips. Two round trips per year - 12,000 miles. Ten years - 120,000 miles minimum on the trailer seems likely, 140,000 would not be unusual. That also equals 2,181 hours windshield time @ 55 mph avg.
As our daily driver on trips, which have included 12 months in 2014 and 2015 as volunteers in three locations - ends up being used more than twice as many miles as towing.
