I'm definitely considering it, but I'm also a cheapskate when it comes to stuff like that.
Do you have any issues reclosing yours in the cold? I had one before that was almost impossible to close cold because it was such a tight fit it must have just barely shrunk. In the sunlight it was fine because the heat would make it stretch just enough to clip shut. This being my winter ride that would be a problem.
No I haven't. I know the problem you are talking about, though. We had an "old school" snap type tonneau cover on our 83, the kind you serew 4000 snaps into the top of the bed. With that one, in the winter, it would take 2 people to get it closed. One to pull on the "tarp" and one to snap the snap........
What I bought is this one:

It has a frame that clamps to the bedrails, and sits on top of the bedrails. So the cover is actually above the bed, if that makes sense. The frame is a big U shape, the front rail has the cover attached, then the two sides. There are bows already attached to the cover, so it doesn't sag and collect water. The rear of the cover has the latching/tensioning mechanism attached to it. When you unroll the cover and get to the back, there are 2 "feet" that hook into a receptacle on the rails (they can be adjusted if more or less tension is needed. Then you rock it in place, and it tensions the cover. The sides are velcro, amd mainly just keep a bit of cross tension on the cover, and keep the sides down. It can be removed in less than 5 minutes if needed. Just remove the clamps with a wrench/socket and pull it off. There is nothing left on/in the bed when it is removed. If you scroll through the reviews ,you can see pictures of mine installed. It's the silver pickup. I'm happy with the cover, and it was not a bad price. I know that some can be a bit steep..... so this wasn't bad. I do use my truck as a truck, so being able to have the full bed open is important to me. We did a scrap run, then a dump run this weekend, and just rolled the cover up and started loading. We also use the truck for our grocery runs, everything stays dry and doesn't blow out. Plus, you can't see inside the bed, so no one knows what it is there, and you have to open the tailgat to be able to pop the latch to open the cover. With the newer trucks that have a lock on the tailgate from the factory, you can't just pop a few snaps and look in the bed.
Sorry about the long post.... but a topper is nice, except when it isn't (like your examples), and I had access to a truck that had one of the fiberglass solid, 1 piece bed "lid" and I will NEVER own one of those...... that are a huge pain ti the a$$!!!!!!
