Truck beds are sometimes vulnerable on two fronts: lack of security and exposure to the elements. A bed cover can change that.
But deciding on which cover to use can take some time depending on your needs, DIY skill set and budget. After doing some research, I opted to give BakFlip’s MX4 tonneau a try.
The MX4 checked the boxes for a strong, hard cover that aims to keep our stuff dry during frequent Florida downpours and keep our stuff protected. (Check out the later part of the video below to see how the cover has held up in the rain.)

Installing the MX4 can be a one-person job, but two people can make it easier if you don’t feel like lifting the cover yourself which, again, is roughly 70 pounds. Also, it’s nice to have someone push down on the BakFlip rails while mounting the rail clamps to ensure a better seal.
On that note, the biggest part of the project is installing the BakFlip rails which is not that big of a deal. My kit came with tonneau adapter hardware which lowers the Tundra accessory rail down a couple of inches while keeping it available for use.
After removing both Tundra accessory bed rails—easy work thanks to a cordless drill and Torx bit—I fastened the tonneau adapter brackets to the accessory rail and then bolted the brackets to the original accessory mounts using the cordless Torx driver. It’s far from rocket science.
The BakFlip rails are pretty ingenious. Not only do they provide four securement points for the cover (including the anchor brackets), they also feature small gutters to channel water to either end of the bed. Drain tubes included with the kit attach to the rails at the front of the bed which can be routed to drain outside. Some pickup owners just drop the tubes into the bed but since we get so much rain in Florida, I routed them through the bed wall plugs (check out the video and picture to the right).

When it’s time to haul tall cargo, the tonneau can be folded up against the back of the cab and secured in place with prop rods that nest along the BakFlip rails when not in use.
To remove the cover, fold it up against the back of the cab, unthread the two star knobs by hand under the cover at the front of the bed and lift up the cover from the BakFlip rail mounting brackets. I did it comfortably on my own.
Frequent rain here in Florida this year has provided plenty of opportunities to get familiar with the MX4’s ability to keep the bed dry. If the rain is fairly heavy, then I can typically expect to have some minor leaks in all four corners of the bed (check out the video below).
Since we get plenty of rain, I chose to run the gutter drain tube through the bed wall plug. Some installers just opt to drop it into the bed.Tom Quimby
BakFlip’s MX4 price tag of roughly $1,000 may cause some wallet cringe, but for ease of installation, protection from the elements and load securement, it’s well worth it.
One of the best features of the BakFlip’s MX4 is load securement. I find myself using the bed more and not cluttering up the back seat with all my family’s stuff, especially on road trips. After locking the tailgate, I can comfortably walk away knowing that the contents are secured and that the kids don’t have to deal with stuff that was once piled in the back seat.
