Since they were never tasked with long range escort the need never arose too often. I know the Mustang IIIs did a fair bit of the escort for the daytime Lancaster raids in 1944-45.
I would say most sorties were DT free in 2 TAF as most of the sorties were within range of internal fuel, although they were used "commonly" when the need arose, by ADGB and 2 TAF. 30 gallons were plenty most times, and I doubt they ever used the 90s in France/Holland/Germany.
When ToD comes along im sure it will be a fuel burn that will be not as severe as the MA.
I think the 30 gallon is the right choice, as its the one they used most often, we are trying to stick to that theme, not "every loadout possible irregardless of how rare" < which I for one dont support, on any of them.
