I've only set it up in the basement but yes the front is an inch or two off the ground when flipped over. I did find out that the holes along the sides are for the tow rope to be threaded through and then knotted at the open end of the shanty. I still think it will work ok when I'm fishing a trout /panfish lake here alone.
I'm not sure if there is much room in front for a heater when flipped down. Did you try it with one today, and it appears the only other place it would go is under the lawn chair and I don't want to do that.
