6D. No Grip. Carry extra battery. The one battery should get you an entire day's worth of landscape shooting, though.
My lightweight running kit is a 6D, 40mm f/2.8, 17-40L, 135L and a Joby flexible tripod, with a couple of cards, a brush, and lens cloths all in a Lowepro Flipside 10L. I can run all day with that (not kidding...have run 6 and 7 hour runs with it!) and have all that I need in remote places to take great landscapes and running action shots. I use the 6D over the 5D Mk III due to the built in GPS and wi-fi. Anyone who tells you you can't shoot action with a 6D is wrong. Yes, there are limitations that only my 1D Mk IV with a 300mm f/2.8 will answer. But this isn't about limitations...this is about freedom of movement and total capability. If I really want some serious landscape shooting, I'll toss in my grad ND filter kit. Sometimes I'll toss in a 580EX II with a pocket wizard flex system when I'm shooting runners on trails, but that gets a bit tight and heavy in that pack.
The 6D is a fantastic camera in a landscape and mild lifestyle shooting role. The AF module may give up a lot next to the 1D or 5D Mk III, but I've found it more than adequate in sports tracking situations, though usually using just the center point. For landscape, this will not be a limitation. If your composition has a main focal point outside the focus points, just use live view as someone noted. This is probably the preferred way to shoot a considered image like a landscape these days, in my view. I use the viewfinder when I have people in the shot. Otherwise I'm tethered or using the live view LCD.
Grab a couple of fast 32Gb or a 64GB card and call it a day. My 64GB card gives more than 1999 RAW photos on my 6D. Heck, I'd probably have a hard time filling up the 32GB backup card on a day on the trails. I just don't run through cards like I do when I'm shooting high speed bursts on the 1D or 7D.
My recommendation is to forego the grip unless you're doing a lot of people shooting. As someone noted, it makes the camera less stable on a tripod. And the alternate hand position just isn't necessary in landscape shooting. It's one of the last things I'd think about given your shooting parameters.
And don't underestimate the little 40mm pancake as a single super-lightweight package on the 6D. Sometimes I will go out with that and nothing else. It's pretty fantastic for landscape and street shooting, working within the limitations of the single focal length.
