If you really want to stick with DSLR for your full-frame, you should consider the Pentax K-1 Mark II: currently available new with a D-FA 28-105 lens for right at $2,000.

Advantages over any Canon/Nikon --
5-axis, in-body shake reduction;
Dynamic Pixel Shift Resolution mode, an innovative technology that takes advantage of slight fluctuations of the subject's position during handheld shooting. The camera closely analyzes four captured images and detects camera shake during handheld shooting before synthesizing them into a super-high-resolution composite image.

It's also built like a tank, dustproof and weather resistant. This is one of the cameras you can dunk in the river and come out shooting. It's consistently rated as one of the best (often the best) cameras for landscape photography. https://photographylife.com/best-camera-landscape-photography#pentax-k-1-k-1-ii

I'm a sort of off and on amateur, when I went full frame years ago, I got a 5Dc and I've never been sorry, as it does all that I require. It's 12 MP are more than enough for 8x10 printing (my fav size). I field trial bird dogs and spaniels (two different venues/trainers etc.) so lots of dogs (a few moving) and landscapes, maybe a portrait or three now and then etc. Plus anything that catches my eye, of course! :-) Harry

With an electronic viewfinder, you get a true depth of field preview as it will be exposed as opposed to being very dim if the lens is stopped down at all.

Additionally the electronic viewfinder can use focus peaking, where it highlights in red (or other programmable color) the edges of what will be in focus.

Finally, the electronic viewfinder can magnify the image in the viewfinder while focusing manually on the subject.

If you focus manually, mirrorless cameras have some huge advantages.

Just so the OP doesn't get the wrong idea, on the RP you have to press a dof preview button, I set my movie button for it, on Sony I think it can be set to always show DOF, but I'm not sure.

I would like to thank everyone for their input and advice. I have purchased my first full frame and ended up with the 6D Mark I. The Mark II was still a little out of my price range and with lenses, I just couldn't make it work. After much research and all of your comments, the 6D is a significant upgrade from what I have now (T2i) and will provide me with more than enough tools to take my photography to the next level. I was able to acquire two lenses as well. Tamron 28-300 f3.5 and a 35mm f2 prime. Again, Thank you all!

Congratulations on your new camera. If some of the features mentioned above such as focus peaking, or an intervelometer or raw histogram speak to you, take a look at Magic Lantern - free enhancements for Canon bodies. I think the 6D is supported.
