When we bought this RV at Fun Town RVs in Denton, TX about mid-June, we were told it's wired for 50V but only has a single AC unit. So you can install the 2nd unit, no problem. The RV (never used yet) is in Cleburne while they try to install the 2nd AC unit. It will have to be RE-PLUMBED before they can install it, b/c they didn't arrange things correctly inside to accommodate the 2nd AC unit. Bad design and now we are still trying to get it done so we can take our first trip. And still keep the warranty in tact. ARGHH!
