I don't really know if you can carry these bars with you. However I recently got this one https://www.amazon.com/gp/product/B0798J8ZP1/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 which is far better than the traditional cantilever bar because you cannot do wide grip pull ups on the kind that you linked (also had that one) - your elbows will hit the door frame.

I have this model of the door pull up bar which is good for chin ups but I feel my arms don't have enough room to be wide enough for the ideal pull ups

This model seems better suited for pull ups because one can spread arms wider :

Thoughts?

I don't have this model and since I have the first model already I might get get by with it unless you suggest that the wider grip one is the way to go.

The pull up bar is in a different room from my primary workout room so if I set up the TRX, it would be using the door anchor that keeps it in place when I close the door. I'll have to see if they get long enough for me to be able to get an incline low enough with the door closed to be equivalent to the inverted rows bar.

I am using this Ikonfitness Pull Up Bar. Which is easy to put up and take down.
