i like mine pretty well and i dont really have any complaints about it at all. but i have heard that because the rear cover has no ribs like a normal tonneau cover does, that when it rains hard it will pool on the rear cover and eventually get into the bed. i havent experienced this yet though. it does make a huge difference in the effectiveness of the heater for the cab. but it also decreases your ability to carry more than 2 passengers (not a problem for me) thats all i got on that subject. let me know if you have any other questions!
