Absolutely will buy it again and only with a Rambox. I had a 2015 and 2017 Rebel without them and my 2019 with the Rambox. Definitely a very functional feature. Bed is always clear of junk b/c the wire ties, tie downs, jumper cables, etc are are neatly organized and stored in the Rambox plus gives great functionality to the kids and wife for storage i.e. soccer balls, cleats, etc. Easy access as well. The warping, is not that bad. Many people don't even notice it. For example, I did not notice it. It did not bother me and it still does not bother me personally. If it can be fixed then great. If not I don't really care. It's not an "issue," per say, in my book.
Hey, these reasonable opinions have no place on the internet.
