They drain out the bottom. You need to see how much clearance you have between the BOTTOM of that plastic and to roof of the RV. After a few years, it is not uncommon for the AC mount gasket to partially collapse and it drops the 2 drain holes to close to the roof. This means you need to replace the AC gasket. Also, it is not a good idea to tighten the mount bolts on an older Coleman AC as this is one way the gasket collapses too much and stops the drain. There is NO need to drill out the holes larger as long as the gasket is correct. Larger holes will mean it is easier for insects to get in and build nests. Doug
