Ok, now that the forum will stop complaining about pics...
starting point:
now they're not linked (damn rentals and what was I thinking with buying a dodge?
) so angles are off, but spacing is pretty close...
so, what I need to work on, is adding about 2' to the cab profile, and adding a deflector? Should I worry about doing a tonneau setup on the bed at all? Or would that be counter productive? Like I said, my one tow with this setup had a plastic toolbox with my electrical tools (5ish lbs) literally getting airborne by the buffeting it was getting on a flat smooth road... had to stop and relocate it into the cab, so it didn't go missing (and with my luck - take out tires)
Extension/deflector, if I build like a 18wheelers daycab, peak about where the RV roofline is? Stick to truck width tapering as it goes up and back?
