BBQ Masters!!!!

Dear Masters of the BBQ,
I am trying to figure out how to cut down the overly big BBQ's that are sold today into on the fits for a teardrop. Does anyone have experience trimming those outrageously large cases they put BBQ's in. Geez, some of them remind me of the huge boxes they used to put speakers in. Boxes sized for mini-minded buyers out to demonstrate other sizes, which had nothing to do with sound quality.
