I know my "32 foot" bumper tow measure is the inside walls of the box (32'). The actual end to end is a couple inches over 35 feet.
It does mean it's well over 32 feet but it's never been a problem, I just insist on the longer spots (40) when in a campground. Most of the time I'm in the desert and it doesn't matter at all.
Don't take life too seriously, it's not permanent.
