freebeard : Still puzzling with the those two options - straight to the corner (easier, more room, no sharp corners when opening bed door etc.) vs. rolled / blended sides (reduces "sharp" corner between the top and side walls -> tiny vortex, more complicated split line between the cap and cap door but could be a tad better from aero perspective).

So key thing is to keep in mind how to shape whole cap while making sure that it can be also finished (continued after prototyping) and the main cap shape and the cap door shape can be split / separated "easily" and then finish. But main focus for now is to make prototype(s) and get proofs of improvements, and then focus how to make finished one.


Rolled / blended sides as shown on the pics is just one option (they are straight lines looking from the top of the vehicle). More complicated option is to make the view from the top also "tier drop shape" but lets see... And yes, there will be a cap door, almost whole top surface (at least that's the plan) but it's limited to bed length at the moment. The extension piece (when bed door is open as shown) is now planned to be separate piece which can be taken out as needed (to further improve aero -> especially for long distance travels).

JulianEdgar : Was planning to do a half truck tuft (longitudal) test before anything as a baseline and then see what happens with the cap + mods...

In general, after reading this forum (thanks for the Admins, this is great stuff), I am confident that improvements can be made and that they are effective.... just need to get data from my own vehicle.
