My 2003 2720 VIN is located on the tongue ("A FRAME") on the inside of the of the street side frame, about as far back as the propane tank, it's on a plate. There are a couple other spots they may have put duplicates VIN numbers.

On a sticker with the weight info on the street side around mid way back on the camper. You may find the sticker very faded and unreadable if it was stored outside.

I have been told by our DMV that most commercial manufactured trailers have the VIN stamped on the center of 2nd or 3rd cross frame member from the rear.

Somewhere in the mid to late 2000's, I believe DOT required it to be on a sticker in a cabinet or on inside of cabinet door with the VIN and actual weight as the camper left the factory. I think it is normally under the sink. I have not found this sticker on my 2003.
