I recently bought a 2018 XLT Max with the tow package and also want to add skid plates but have not yet found the Ford parts online.
Attached are pictures I took of Expedition FX4 skid plates, generally they do not look all that substantial.
The one under the intercooler appeared to be steel, under the engine aluminum, under transmission appeared to be aluminum with that fiber stuff on it, transfer case plate was steel, and the gas tank shield was plastic.
I contacted RCI for heavier duty aftermarket plates and here is their response:
Thank you so much for your interest in our products. We manufacture a front skid plate in steel and a transmission skid plate in steel or aluminum. Unfortunately not a transfer case skid plate.
The 09-14' F150 happens to share some similarities in the frame with the Expedition. So, that's why we sell the front and transmission skid plate.
We only manufacture the skid plates for the 09-14'/F150 in steel. However the transmission skid plate is the same for all 09-19' F150s. That is why we have one in aluminum that fits the Expedition.
I'd be happy to place an order for your directly or feel free to place one at the website and let me know if there is anything else that I can help you with.
Thanks again and have a great day.
