Yeah, was gonna build a tractor/implement shed maybe 10-12 years ago, just never got that round tuit.

Now most of the materials I'd bought have been used for other projects.
Agree on tarps, maybe 2-3 years for a good one, cheapo HF ones you're lucky to get a season out of 'em.
Didn't know HF sold them, but I've got a couple Shelterlogic ones. I'd recommend putting a sacrificial tarp over the tent while it's still in decent shape. Need to replace it every couple years, but it's a lot cheaper (and easier) than replacing the tent.
How well do those radiator hose heaters work? I've heard everything from "pretty good" to "don't bother". My Kioti can be a bit cold blooded.
