How much of an air conditioner does my RV need?
While you don't want to overspend for a unit with more capacity than you require, you also don't want to purchase one that is insufficient for your purposes.
Most RVs will likely need a model with 13,500 BTUs in moderate climates.
However, if you have a larger RV and intend to travel through hot, humid regions, search for a unit with a higher cooling capacity, such as one that can produce 15,000 BTUs or more per hour.
By purchasing a unit with less cooling capability, you can frequently save a few dollars when driving smaller RVs in moderate climates.
