Are you always so acerbic?
What 120 acres was referring to is the advice that many shelter companies give to park your vehicle over the shelter so that it keeps debris from falling directly on the sliding door.
The vehicle provides a support to elevate rafters, ceiling joists, and the like off the floor.
Now, if some of that debris was to puncture the fuel tank it would be directly above your head.
My solution is to park a vehicle directly beside the shelter.
That way I still get most of the benefit of a raised support structure but the leaking gasoline would run around the shelter door.
Here are some pics of my ground zero install last Fall.
Yep.
And that car parked beside the shelter isn't going to move - almost as likely as a gas tank being ruptured by falling house timbers.
