I would agree with you as well. When you blow in the insulate you will get settle from pulling the trailer on the road or gravel roads. When you use Pink Foam sheets that makes a stronger insulate and will not allow gaps.
One thing you could look into is Spray Foam Insulation where it will harden when sprayed on. But make sure you do electrical and everything you want to run in the walls before you spray foam because it will be no fun trying to run wires in harden spray foam.
Good idea on the electrical underneath but you not sure what you would gain from that because you will still need to come up the wall from the floor. So it is a horse a piece discussion.
