AirSkirts tubes will change pressure with temperature fluctuations. When it’s warmer, or the sun is shining directly on them, the tubes will expand a bit, and when it’s colder, they’ll lose some volume. There’s a pressure over release valve which will keep the tubes from bursting or lifting your RV, so no need for worry there.
Unless you’re experiencing very large temp changes in a short period of time, you shouldn’t have to do much maintenance on your skirts. We suggest inflating them when the weather is about average. Always inflate just until the tubes hold in place by making contact with the I-beam or underbelly of your RV. Always be sure to inflate slowly underneath pipes, pull handles, and similar protrusions.
Using the carabiners and straps included in your welcome kit to attach your tubes together by the D-rings on the ends will provide extra security in case you do have a sudden unexpected cold snap.
If you need to add air, just use your air pump. To release air, open the valve and press on the center spring.
