I don't remember hearing him say a 'dual' wall during the campaign. Even if he did, most of the time it was just 'wall'. And there's not a big difference between a wall and fence.

If you've crossed the TJ border you know the difference between a wall (portions adjacent to the crossing) and the fence (portion you drive parallel to as you head to Rosarito.
Those metal fences currently up are completely useless. But yeah, a fence will do the trick.
As far as the dual wall goes, I recall someone talking about it. Must have been one of Trumps surrogates. Either way I've always felt it won't get built, because it
wouldn't stop folks from coming over...oh and tunnels. 
If there was a same size (height/thickness) wall there instead of fence there isn't going to be any difference in effectiveness.

Its not whether its called a 'wall' or 'fence' that matters but its size & composition along with the other security measures/layers (BP agents, sensors, cameras, aircraft, drones, etc) But keep making a big deal that Trump said fence along with wall..
I was saying this past summer he should say 'fence' instead of 'wall' because there wasn't a big difference between the 2, it was just semantics, and it sounded less harsh. Post election with the left still in full meltdown mode Trump is clearly trying to sound more moderate & presidential in his tone.
As far as tunnels, those aren't being dug to smuggle people.

Not worth the trouble. They are being dug to move drugs. The cartels don't want thousands of illegals knowing the locations of their tunnels. The tunnels are located on only on a fraction of the border, mostly urban areas in CA & AZ, not the rural areas of CA/NM/AZ. With TX (1250+of 1900 miles) there is the Rio Grande. No one is tunneling under a river. 99+% of the border crossers aren't crossing through tunnels.
And remember there is zero chance at so called 'comprehensive immigration reform' until the border is secure however that is done and however long it takes.
