Tonneau covers that don’t leak

I just bought a 2016 Ram 1500 with the 5.7ft bed. I ordered a roll up bedcover off of Amazon called Gator. its been on for about 2 months now and ive only seen a couple drops in a very hard rain which may have come from when I opened the tailgate. there is a weather flap that goes over the tailgate. you leave the back edge popped up, close the tailgate and then push down and the cover locks into place. its held down with velcro along the sides the quality is good and im very happy with it for $215.

I have a UnderCover SE on the wifes 1500 chevy short bed. Nothing get wet in the bed. https://undercoverinfo.com/undercover-se
It weighs just over 50 lbs and is easy to remove. I added a tail gate seal to stop dust and fine snow that can sift in small cracks.

The Retrax tonneau cover that I got from 4wheelonline doesn't leak.

I have a Lomax cover. The cover does overlap the front and back of the box. But since it is a between the rails cover it doesn't overlap the sides. But I guess it must have seals or something, I don't know. All i can tell you is I have had it for 2-1/2 years and there has never been water inside the box. My truck has sit outside every minute of it's life (winter, summer, snow rain) and it goes to the car wash at least 30 times a year.

Sorry, I missed the "hard, lockable" requirement before I responded.
Hopefully someone can give you a review of those.

I occasionally carry things in the bed I do not want wet at all. Hunting trips mean duffle bags, sleeping bags, pillows, guns/bows, bags of corn, etc. Or a vacation trip without RV means luggage. I had a full hard fiberglass cover on an earlier truck that overlapped the bed rails and tailgate. No way for any water to leak thru at the top. Only possible place was to blow in the small gap between the side edges of the tail gate and the bed. But I also had a Bed Rug that closed that off.

A few small drips shouldn't be a big deal with those items and shell won't necessarily be much better.

Luggage for example: If you've ever flown on a rainy day, the bags wind up out in the rain as they get loaded...but we've never had an issue with the clothes being wet when we get to our destination.

If there is an item of particular concern, pack it toward the center of the truck bed.

Although I rarely ever carry anything higher than the bed rails, that is a problem with the solid cover. I don’t want a camper shell type cover.

When I say doesn't leak at all, I mean no water at all gets into the bed. I have a roll type hard cover but it leaks around the ends of the tailgate/corner of the bed when it rains. And that water runs toward the front of the bed due to the forward tilt of the truck.

For those who said their covers do not leak, how do they prevent water from getting in around the tailgate since they do not fully overlap the tailgate and the gap between the end of the gate and the bed sides?

Idk, I’ve had similar soft, tri fold tonneau covers on the last 4 or 5 trucks. Including the last 10 years here in Wetstern WA. Never had stuff get wet.
Can’t swear that a drip or 3 doesn’t make its way in somehow, but literally never had anything get wet.
I think if you’re that worried about moisture, a SUV maybe a better choice.

Unfortunately Lorax only offers a short bed model for GM HD trucks.

In 40 yrs of owning pickups, have never had a bed cover until I bought this used 2014 GM 1500 which has a roll up version
As noted, heavier rain and wind seems to be enemy at back two corners. Only thing I can think of to fix, is adding some more, replacing exhisting rubber gaskets with thicker rubber.
After looking a bit ago, something I had not noticed before. The stake holes are basically covered in front. But the rear ones are 75% uncovered. I would have to assume some of the water I've seen in bed is coming via here.
Reality for my usage, the bed is water proof. As I keep very little in the bed, even when covered water will not harm it. If it water WILL harm the item in the bed, it goes in the cab, or when their is no rain, drive thru car washes in the forecast.
