We consider the monomial expansion of the $q$-Whittaker polynomials given by the fermionic formula and
via the {\em inv} and {\em quinv} statistics. We construct bijections between the parametrizing sets of
these three models which preserve the $x$- and $q$-weights, and which are compatible with natural
projection and branching maps. We apply this to the limit construction of local Weyl modules and obtain
a new character formula for the basic representation of $\widehat{\mathfrak{sl}_n}$.
