Isabella tent info sought

Romana

When we bought our 2006 DM T@B a few years ago it came with a tent, but we never tried to set it up before last weekend. We didn't even know what brand it was, but we assumed it to be a Therma-rest. Well last weekend we attempted to set it up, and it turns out based on the pole design it looks like an Isabella. We actually love it, but would like to hear from any others who might have the same design. It appears ours is a very early model, perhaps even a prototype. We have no instructions, it has no floor, and there are no labels of any kind. Attached are some pictures for your perusal. Thanks for looking.

That is quite unique!  I've seen lots of T@B tents and awnings over 14+ years of ownership and teardrop rallies and have not seen anything like it.  The pole set design is definitely not Thermarest.  I'd have to see the poles and set up to tell if it is similar to the several Isabella designs I have seen. 
It looks like a nice design and you seem to have setting up figured out.
Have fun...
