When the party cleric is also a bard:

Cesare Bonizzi, also known as Fratello Metallo, was a Capuchin friar who used heavy metal to “spread the word”

A CC-177 Globemaster III, in case anyone is wondering what plane.

Like all “heaviest [thing] pulled by person” records, the impressive part of the act was the engineers that designed the wheel bearings (and that the canadian air force let some rando touch a Globemaster III…) but this guy does have some legit impressive lifts to his name otherwise.

His body was upgraded from temple to Fortress Church.
