I think Vultee XP-54 twin boom was copy of P-38 design. Main landing gear was retracted to the boom same as P-38.
Vultee studied P-38 design through XP1015 failure.
While XP1015 had intercooler, radiator and oil cooler at the outboard wing, XP-54 had intercooler, radiator and oil cooler at the inboard wing nevertheless single engine.
I imagine that XP1015 intercooler, radiator and oil cooler position is little hard, because outboard wing is thin.
Perhaps it 's good to locate radiator at the engine nacell same as P-38. But perhaps Vultee wanted to realize his idea.
So it was impossible to have fuel tanks at the inboard wing, all fuel tanks were located at the fuselage, XP-54 fuselage became very large. XP-54's weight was double campared with P-51. XP-54 was a longest single engine fighter at the day.
Expected maximum speed of XP-54 with cancelled P&W X-1800-A4G engine(2000hp) was 821km/h but only marked 621km/h with XH-2470 engine(2300hp). P&W X-1800-A4G(H-2600) engine was a non turbocharged single stage two speed mechanical supercharger with aftercooler sleeve valve engine. You can see aftercooler in the following X-1800 engine picture.
XP-54 had ultimately slim boom.But we digress. ;D
