This is a Trailex trailer. It's 6' wide and 12.5" long. It only weighs 500lbs and can carry 2,500 lbs. I have straps and a spare tire to go with it. I've actually never used it. I bought it a couple months ago, but I've decide to take a different path on racing.
My trailer is older but this is the closest, current Trailex model.
PM me for pictures.
