Hi cazw66, welcome to the forum.
Sounds good. Maybe put some bedding material in the vicinity of the house also as they often like to bring in their own material. I put a couple of small planks against the side of my hog house (to keep the rain off) and stuffed a load of hay underneath for them to use, my resident hog also steals bedding material from the other hog house which is not currently being used. I put a mixture of straw, hay and dried leaves in the hog houses which they seem to like. Your hog may be building a hibernacula to hibernate in over the winter.
Maybe get a wildlife camera if you want to see some closer up footage of the hog.
