I agree with Doc. If you didn't come with at least 50A as an option I doubt that rear vent is braced for an AC. Your electrical service definitely won't be up to the task of running 2 ACs in tandem.

As far as electrical, as Doc alluded to, some run a separate 120vac line to run the 2nd ac. As far as adding bracing for it hopefully someone has done that and can expound on what that involves. Good luck. If you've moved to TX, you didn't say where (N TX to most is DFW and N) it can get darn hot...and humid depending on where you are. One AC would not, and does not, work for us. Good luck.
