I'm only guessing, but I think most people who say it's too hard from underneath, haven't slid themselves back far enough towards the rear of the van when they reach for the plugs. I can honestly say it only takes about 5 minutes to get them from underneath if you're far enough back towards the rear. The hardest part is pulling the boots off the plugs since it's difficult to get much leverage, and they've probably not been removed since the van was built.
