Just a question as I cant seem to find the information I am looking for in regards to how trailers are measured.* I have a 4 wheeler which lists the overall length as 72 inches and width as 46.9.* In consideration of the space I have to store it a 6 x 8 trailer seems like it would be a perfect fit for 2 quads side by side with just a couple of inches to spare.* Would this measurement be unobstructed usable floor space or it is like a 2x4 where it isnt either.*
