I think it comes down to personal preference. I personally like the idea of the axis tower because it's all one piece from my understanding. I have a collapsible tower currently and in my opinion - they suck. They wiggle, they creak when someone cuts hard, and in general are not as solid as a contiguous tower would be.
That being said if you don't have the garage door to fit it, you're SOL. I think you'd be just fine installing an aftermarket, but you might want to consider having the dealer put it in or at least make sure you've got proper reinforcement where you drill the tower mounts into the hull.
Otherwise I think you're good to go. I hate collapsible towers enough I'd add an addition to my garage before switching towers
