Fun Finder 139 models

[Willky]

Hi,
I have a 2007 X 139 trailer. I see that there were also some "M" and "T" model 139s around this time. What are the differences in the various models?
Thanks- Willky

I had a 2003 T-139 for several years -- it had aluminum siding and very little insulation. Very well built, thought. Very small tanks.

So I bought a 2012 X-139, new, with fiberglass siding and more insulation. Much bigger tanks. We use it between 60 and 90 days a years, and we take it all over the West.
