I feel you man, I thought I had a pretty good grasp on payload/towing before I ordered. WRONG. My build will work still but if I had known what I know now, my options selection would have been different. When I heard the Tech Group was being merged into Level 1 (possibly for no upcharge for people who already ordered, depending on your dealer), I tried to get that added but they wouldn't/couldn't do it. It is what it is.
The waiting is what kills us, if your truck appeared in your driveway right now you wouldn't give a parachuting goat's @*** that it wasn't a Limited lol
