Our new truck doesn't have a tonneau cover for the bed, and we're thinking that it would probably improve aerodynamic performance (and mileage) if it did. Does anyone have experience with adding one ...
Question for ib516 and the use of the Undercover Flex. I've got a truck similar to yours on order. 2015 Ram 3500 CC SRW with 6'4"bed. I will tow a fiver as well. What position is your cover in when you are towing? Is it folded up and locked down at the front of your bed in a horizontal position? Or do you have to fold it all the way up in a vertical position and use the support rods?
