many copilots elect to stay in the LH seat of a long haul aircraft as a lifestyle choice.
Fulltanks -Not trying to be picky but just trying to avoid confusion - is that a typo..or are you hinting at the amount of time a co-pilot might spend in the LHS as "heavy"?
I suggest that, if you have not previously visited the Gulf, you have a short holiday there in July or August - it's not yet air conditioned outside
