I have a BakFlip on my 2017 CrewMax. I love the fact that I can open all the way, so I can easily use the whole bed, since it will fold up against the back of the cab and lock in place. This leaves about 4" of the bed covered. I would buy the BakFlip again.
I got the Backflip MX4 and folding tool box. Easy install , tool box perfect for tie downs, jumper cable etc. aluminum panels fold up easy and secure the bed and good drain system keeps water out.
It doesn't appear you are ready to get rid of your BakFlip, but if you ever do, the new ones don't require rails to sit flush with the top of the bed. Installed a BakFlip in my 2017 Tundra last year, and it looks nice. Still doing a good job of keeping rain out ( not that we get a whole lot in southern AZ).I bought a Bakflip F1 for a 2010 Tundra in 2011. Ran that truck 210,000 miles until last Sept when I traded it in for a 2020. I kept the Bakflip from the old Tundra and put it on the new one (direct fit). Its a great cover; the F1 model is Poly on top and aluminum underneath. Still looks great.
It's survived 10 New England winters, and a LOT of opening and closing because I'm constantly using the bed of the truck. It does leak a tiny bit now because the seals in between the panels have shifted a bit, but it still keeps 99% of the water out. Rain does not pass through it easily and I've been in some torrential down-pours. Most manufacturers will always say their cover is not waterproof simply because stuff will get wet from condensation alone.
Only gripe I've had all along it that it requires rails to sit on so you get that flush look from the side. I wouldn't give up that look as I think covers that sit on top of the bed sides look like crap, but I wish it didn't require the rails.
I did find a nice headache rack that will work with it from Aries (Switchback), which I'll be adding those on this month so I can add plow and reverse lights up high. I'm also adding some bedside boxes from SwingCase for storage under the cover.
Thanks for that info, OI JB!It doesn't appear you are ready to get rid of your BakFlip, but if you ever do, the new ones don't require rails to sit flush with the top of the bed.
