Best tonneau cover?

I'm looking for a tonneau cover that can fold up in sections (or retracts), locks (securely), and water tight. I do not want to give up the use of the bed rails and do not want to do any major modifications. Also bonus if it folds up without taking up bed space or is easy to remove and store in the cab.

I have been looking just haven't be able to find exactly what I'm looking for. The closest I could find was these two:

Fold-a-cover G4Elite -> hard top, foldable, lock (f&r), mostly waterproof, Folds up & removable with 4 bolts

Will the G4 fit in the cab if taken off?

Advantage TorzaTop -> hard (hard hat) or soft top, foldable, lock (not tailgate), mostly waterproof, stores in cab

 

Extang Solid Fold with the Pop n lock and I love it.
I don't think it will fit in the cab because the cab is rounded.

 

I have the G4 Elite and I love it. I've never had to take mine completely off so I dont' know if it would fit in the cab but I would guess that it might. It weighs about 45 lbs and is pretty easy to move around. I love the way it folds out of the way. I've hauled a ton of firewood around with it folded up. It locks nice and secure and I live in Oregon where it rains all the damned time and it stays dry.

 

Had 2 Fold a Covers and 1 Advanced folding cover over a period of several years. The first Fold a Cover was the the original model, The Fold a Cover I cuurently have is the G4. All 3 of these covers work the same and do a good job, the G4 has a advanced locking and latching system, the G4 will also lock your tailgate, although I didn't use the G4 lock, I have a pop & lock. The folding covers with a lock and a locking tailgate give you the ability to keep things secure in bed (including bed extender). I have the G4 on about 3 weeks now and so far it is a very good cover.

 

A co-worker has that cover and really do like it.
I have the Extang trifecta and its well made. I'd get this solid fold cover if I had my time back though

 

Go with the access limited from truckalterations.com

 

I have the Advantage Torza Top, although not the hard one. Not locking. But i typically don't keep valuables back there. But I like it and have no problems with water getting in.

 

What is a good roll up tonneau that doesn't flop around in the wind? I'm looking for something that is as light as possible, that can be rolled up and taken off in a couple minutes.

 

Thanks all. I think I am also going to get a pop & lock to secure the tailgate.

I would really like to see them before I decide so I am keeping an eye out for someone who owns one.

 

Pop & Lock feels a little cheap. but it works. Even works with backup camera. Easy installation !

Locking tonneau cover and Pop & Lock and your bed items are secure.

 

Bakflip F1 and love it, pop-n-lock color matched SWB - Locks a bit sucky, paint is chipping and the whole mechanism feels a bit flimsy but I don't know of anything better. Do you?
