- Read about adding battery disconnect switch to inside vehicle for convenience - attaches to + battery lead. Any issues vs attaching manual cutoff to - battery post?
- Ford recommends driving under 65mph. What is your driving speed?
- Is a mud/stone guard necessary with our class C? If so attach to RV or tow bar?
- We have a TPMS on MH, any need to add to toad?
- Any other info you want to share from experience?

I am just installing tow setup on my new 2018 Lincoln MKX which is similar to your Edge. Can't comment on all your questions but here are the issues that I know about based on 15 years experience towing other vehicles:
Battery disconnect: Much better to include a charge line from your RV battery to the Edge battery. It can be wired through the same connector that carries your light signals so no additional prep required for towing. Just make sure to include a 15A or (better) 30A fuse within 4 inches of EACH of the two batteries. This will keep your car battery charged all the time and you won't need to disconnect the car battery.
65MPH: I would adhere to this as going faster can destroy your transmission AND your car's warranty.
Mud/stone guard. I highly recommend the
Protectatow guard. It will protect your car and is easy to install.
TPMS on toad? YES. Without a TPMS on toad you can have a flat tire on toad and never know it before serious damage is done. There are numerous TPMS systems out there, here is the one I use and it works well:

You didn't mention a tow brake in the car, and I think that one is necessary in order to be both safe and responsible. You don't want to ever be in the sad position of injuring or killing someone when taking the precaution of using a tow brake would have prevented it.
