13,137 miles over 9-1/2 weeks was the longest single distance trip with one of our TC's.
From West Michigan north to US-2 in the U.P. going west, then up to the Canadian Rockies, on to Alaska by way of "The top of the world highway" and traveled all 7 highways in Alaska, including Fairbanks and north/Denali NP area and highway/Homer Spit/Seward/Anchorage/Valdez/Atlin. Then down to Olympic NP (WA) and California and then on to 8 National Parks on the way back to West Michigan going back to US-2 to avoid the insane Chicago area. 3 other slightly shorter trips in the same basic directions also but this was the longest single trip with a TC.
5th longest was West Michigan to Bar Harbor ME/Cape Breton Island Nova Scotia Canada/Washington DC/Blue Ridge PKWY/Myrtle Beach SC/Smoky Mtns NP and Cades Cove/Branson MO/and back to West Michigan, 9,874 miles. Lots of side roads traveled.
