That would be really nice of you to add the belly tank as an option. On a second, lesser note: since it does not carry ords, should it not be a fighter-only mode a/c; much as the Yaks & C.202/C.205 are set-up? 
Thanks again for adding another a/c to the line-up! 
There are a number of fighters that fit in the "fighter only" category that are currently mixed ftr/attack. The Spit 5, 9 and 14, and the 109E-4, F-4, and K-4. And now.. add the P47M to that list. Unless I'm mistaken, all of those mentioned were designed to be air superiority fighters or interceptors. Obviously, when the skies were cleared those units who were bored were sent on strafing-attack missions.
Also, the TBM is a bomber only, when me thinks the direct fire rockets entitle it to be an "attack" plane as well. Ah well...
