Your heat loss through the floor is probably not real bad, the biggest problem is that it is so darn cold when the temps are low.
I opted out of the spray foam option for a couple reasons, wanting to do work under the trailer, cost (though this was not a big deal), and I don't care for the looks. I have since found that just using a mat on the floor makes a world of difference.
What I do plan to do when I have the time (and who knows when that will ever be) is to adhere 2" rigid to the shell where it is open, leaving a bit of a gap around the edge and protrusions and fill this in with a good spray foam.
