Spenom –
As you can tell by my username, I'm a big fan of the 139 model. The "139" refers to the length of the box in inches – i.e., less than 12 feet! You got a great deal on that 2005 unit – well done!
When we bought our old 2003 T-139, we had never done any trailering or camping and bought it as a tentative experiment. To our surprise, we fell in love with camping, and have camped for about 60 to 90 nights per year since 2005. In late 2011, we sold our old T-139 and then bought a new 2012 X-139, which is our current trailer. It looks exactly like the one pictured at the top of this page.
If you are interested in finding out some of the places we've gone with this little trailer, check out our blog:
Look, Mom, We're Camping!
And if you are interested in some of the modifications we've made to the trailer, check out our other blog:

In any event, be sure to ask questions – we love to answer them, in order to save you from some of our own mistakes. Also, I note that you paid for this trailer in Canadian dollars, which is a hint that you might be in Canada. Where do you live? We have traveled to Alberta and BC and hope to go back east someday soon.
