To tint or not to tint. That's the question.

We have a 2012 International Serenity & even with 2 ac units on top, it gets hot in the south! I've just recently added thermal liners (using Velcro for easy removal) to our very thin curtains but our big side windows only have roller shades & these get very hot. Should we attempt to remove the screens & add window tint film or is there a better solution? I'm wondering if removing the screens & reinstalling will cause problems down the road. All suggestions welcomed! Thanks.
