So there is the number "20" just outside the door. Does anyone know what this is? I noticed it on another picture of a barth. I also noticed on my data tag "MC20" and on the other picture I saw they had the number "25" and their data tag had MC25". Does this mean anything? Is it from the factory? Thanks

WOW!!!! Funny when you post something and you realize you did not even think a little about it. Mine is 20ft hence the MC20 on my data tag and the 20 outside the door. The picture I saw was a 25ft hence the MC25 and the 25 outside the door.

So the numbers must have been put on at the factory right? I wonder what made them think to put it on there? I like the number, kindove looks like an address number.

If you have not decoded your data tag, 74101586MC20A.
