I've been trying to decide what to put on my new truck. Hard or soft tonneau or topper?
I've had a couple of toppers. They're handy for sheltering larger/taller objects (including me). The big downside for me is that the back glass is always dirty. I travel a lot of dirt roads and the back glass is always obscured. In fact, a topper does a pretty good job of obscuring vision to the rear even when it's clean. Also, they are a real pain to remove and re-install and, of course, are the most expensive option.
I decided when I bought my Dodge that I didn't want a topper so I went through the researching process on tonneaus. The soft covers are the cheapest but don't have the security of the hard covers. The one piece hard covers weren't in the running. I bought an "Advance Cover" (pics in reader's rigs) and have been very pleased. It seals very well, even dust. "Fold a Cover" looks to be the same cover but made by a different company (in the same city, I think). These are priced between toppers and soft covers.
I really prefer the tonneaus. I like the visibility out of the truck. But, sometimes, like today, I need a topper. I've got to haul some pretty expensive lab equipment to CO. Most of the equipment is in the cab but the rest is in the box with the "Advance Cover" folded up. Some of the stuff is too tall to fit under the cover. So, I have to wait for clear weather to make the trip. So, it looks like I might buy a soft cover and the cheapest (Unicover) topper for those few times I need it. Unicover (I think that's the name. Ugly, aluminum, boxy toppers) are the cheapest covers made which is fine as it would be stored on the ground in the back yard most of the time. I don't think the "Advance Cover"/topper combination would work due to all of the mounting hardware but I think the soft cover might.
