Hauling the bike in a F150

Well it looks like I have to haul my bike instead of riding it home. In a little over a week from now I will haul my ultra classic to Winnipeg, from BC (about 1200 miles). Drop it off and return with my 2012 road glide.
I have a 2014 F150 that I will be making the trip in. I was looking at the tie down loops in the truck https://encrypted-tbn1.gstatic.com/...sgr8UXAit1nWNP8_-psmVUsiWbtoEEecpJ05BagX-TzLH
Same as this style.
There are 2 up front and 2 in the rear all down low. I have added some rail tie downs as well.
Does any one know in these stock tie downs are strong enough for a 2400 mile round trip?
I am pretty sure that they are just mounted through the bed, not through the frame.
