Deluxe Log Cabins

Have you ever driven by those highway signs showing the log cabin you can build or have built? They usually look nice on the outside but I always wondered if it would be dark inside since they don't seem to need sheet rock and paint. So here are some pictures I found online of "log cabins".  These are maybe a step or two up from the ones advertised on the highways. I think I could live in most any of these.

Could you make do with any of these?
