[VAC] Re: locating leaks

The fact is that 'positive pressure' doesn't require the trailer to be
'air-tight'... it just means that the pressure inside the trailer needs to
be greater than the pressure outside. With a blower moving sufficient
amounts of air into the trailer, one could leave the vents, windows, door,
etc. open and still have 'positive pressure'... Closing off those openings
just makes it easier to achieve.
