yes it is very low to the ice, the double layered insulated floor is 2" thich & it all sits on 2x4's laying flat for skids.
I wanted to be as low as i could be for seeing the holes.
it's sitting high up on blocks right now for that very reason.
when I get out again I'll drag it over on a fresh spot, drill holes & enjoy another weekend.
I keep my portables handy for the mobility but I'm suddenly spoiled by the comfort of an insulated house.
