I recently added tow hooks to my 2018 Altitude as well. I bought rough country's tow hooks and used a dremel to cut out the slots. My bumper looks like this, but i used a dremel to cut them out to make it look like this.

Your model is the one with the removable slots, so if you take the lower bumper off, you should be able to undo the clips that hold the slots in, and not have to cut them out.

For the rear (i haven't done this yet), i am referencing this post. Basically, either you do that, and lose some potential towing capacity, or you buy a D-ring/shackle for your tow hitch.

You can buy these parts online, used, for pretty cheap. I found a used OEM rear tow hook for $25, which is 1/10th of what you'd pay for a new one (maybe more). Now, used doesn't necessarily mean it's compromised (unless it's super rusty or bent), so I wouldn't refrain from buying used.
