I tore so much industrial strength junk out of it. The seats? They were incredible, built to last many years of transit system abuse. Another example, a wheelchair lift that looks like it came from an aircraft carrier, and could lift an aircraft. I don't see ever re-adding that much weight. The most significant thing I've ever had was 300 gallons of potable water (and 8 companions + gear) for our last trip to BRC.
