If I remember right the measurement is basically 8' long by 6' wide. It pokes out about 4 inches on either side of my Toyota pickup when I tow it. I don't have a picture of the inside of the trailer and might not be able to get one for a few days so I drew a layout of it inside so you can atleast know what it's like. I tried finding a pic online but couldn't, sorry.
I will get a picture ASAP.
This is not to scale or precise or anything, just for general layout purposes.
