You probably could build a lighter trailer, but would sacrifice quality to get it.
Once I get this foamie built it will basically be a unibody. Quite rigid and durable compared to the coroplast. Not to mention a lot more insulation to keep you cool or warm in different climate conditions.
I wasn't thinking the cheap/soft/weak stuff used for political yard signs, USPS mail trays/tubs. I was thinking more of the much higher strength corrugated polycarbonates. Those panels are VERY strong and rigid. Like I said, they make commercial greenhouses and sunrooms out of the stuff - (think snow load here near the Great Lakes) BUT it isn't cheap.
