Skyl4rk's my name and Engine Off Coasting's my game.
Below is a reasonable facsimile of my Toyota pickup. After watching the vids and checking out the mini hurricanes which form over the bed, it will be obvious that a boattail is desperately needed. However at this time my options are tailgate up or down.
I find it difficult to interpret the vids, however one thing is for sure, the back of the cab is a major problem, causing lots of turbulence. Vids were done at 2,500,000 Reynolds.
What say ye? up or down?
