I found that you can reach the drivers side front plug #1 through the wheel well. Plugs #3 and #5 I was able to reach from under the van, these are the middle and back plug on the drivers side.
I was able to reach the passanger side plugs #2 ,#4 and #6 through the passenger wheel well. Plug #6 was a bit tricky, I used in order a 5/8' spark plug socket with swivel attached, a 3" extension, another swivel, two 8" extensions.

you can get to some from the front and the ones in the back you can get to through the wheel wells
