I just sold my 2004 Lance 1121 that was equipped with A/C, I only used it a handful of times, but it was totally worth it. My current RV search (Class C) includes the requirement for two A/C units, one unit dedicated to the bedroom is my preference. Of course I live in the Desert Southwest so A/C is not an option; however, most of our camping is done in the mountains or Pacific Northwest where the A/C units rarely run.
