If I remember right, the Poles are on the outside with each pole having its own line? And then 2 internal supports?
With the way the material is on those tents, it's going to wear a hole in the fabric faster than you can think.
If it held up in those conditions, and it still standing, don't worry about it.
If you truly do want an internal frame tent, I would sell the Aklanak, and call Davis for the internal frame tent. Also wall tent shop has a lot of options.
I have a 20 plus year old internal frame 12x14x5 (not certain of the brand). It is now set up for what is its third full winter, and won't come down until March or April depending on the thaw.
