So we've had our campervan for just over 2 years and weve decided that one thing we don't have but would really like is a window at the rear on the passanger side. On the outside of the van at tge rear passanger side is a glass panel. Taking the glass panel off is no problem and taking out the bed for access is no problem. My question is....would it be possible to cut out the panel to fit a window without ruining the carpet ?
