I am looking to build a large bicycle trailer, but nearly everything I see online is either very small, or looks like it would fall apart under just it's own weight.
I am needing a 4'x8' (WxL) trailer that can hold around 400-500lbs safely. Lightweight is a must as I have looked into automobile trailers of that size, but they are all over 200lbs. I need to stay at or under 100lbs (so aluminum?). I am not sure if this is something I could build myself, or would have to buy (if it even exists).
Thanks in advance!
