Do "vented" tailgates help on 5th wheels?

Friend of mine says he gets better mileage with a vented/louvered tailgate. Do they really make a difference or is it just another novelty item that's nice to have but not needed.

*Maybe* an incredibly slight improvement - only noticeable in his mind..:W

The *major* advantage/s of a "V" gate are:

1. Leave TG up when hitching or unhitching.

2. Generally speaking - nobody wants to steal "V" TG.
Exactly the opposite for factory TG. Easy pickins', easily sold.
Viscous circle of supply and demand due to -
Theft, and dented (for lots of reasons - not just trlrs).

3. Generally, "V" gates are lighter than factory TG, easier on-and-off.....PLUS - no big deal if you drop a corner when taking it off.

BTW - "DRM" - I do all the same things I did with the factory TG
with my $150. Northern Tool (Steel) "V"-gate.

Stand on it, sit on it, rest heavy "stuff" on it, use the "V" to center long lumber, etc.
