The Millers extended their unbeaten pre-season with an emphatic win over their Cup final victors.
Although Eastwood have lost their manager and some players since beating Carlton 6-1 in May, this was still an impressive performance against the Conference North outfit.
Steve Chaplin got the scoring underway in the fourth minute by firing home after being left unmarked.
Terry Hawkridge doubled the lead just before the half-hour when he scored a rare header.
Chappo extended the lead early in the second half when he drilled home a cross-shot that nestled in the far corner of the net.
And the game was over 11 minutes later when Massiah McDonald scored from the edge of the box.
The icing on the cake was the fifth, five minutes from time, when Gill poached from close range after Lavell White’s effort was saved.
Carlton Town: Kearney (Marshall 46), Thornton, Fletcher, Darkin, Davies, Large, Hawkridge (White 65), Goward (Shaw 53), Chaplin (Gill 56), McDonald, Hollis (Smith 60).
