Smoke coming from coolant/oil area in trunk

[kk2002s]

Is there condensation on the truck lid above that area? (Looks like it from the pictures with moisture on the rubber seal)
That will also indicate issues with Cap/Purge valve/Tank.
Once you take off the plastic cover is there a white residue around your Purge valve? (This indicates it's leaking)
How is your coolant level?

Smoke from oil fill and dip stick, I don't know about that. Maybe after a longer drive, removing the cap maybe one might expect to see some vapor escaping.

Check your coolant cap. The latest one ends in 04 and yours doesn't look like it does. Older caps may have a weak release spring and allow pressurized coolant vapour to escape. Get new one regardless P/N 99610644704.
