This is a thermodynamic issue. Ford says the Lightning has a range of 300 miles. Average mid size travel trailer weighs about the same as a high end F-150. Double the rolling mass (truck plus trailer) reduces range by half. Can't fool Mother Nature.
That would work for lots of folks around here. Friday night 5:15 on the road headed to the lake. Setup by 7 and drinking beer. Sunday at noon headed home, trailer parked in the driveway and mowing the lawn by 1:30. Next week, rinse and repeat. ?.
