Just can't worry about the things that we have NO control over! That a side, we have given it thought and the motel/hotel/cabin rental would be your friend until any repairs and/or replacement. When camping when it is hot, inside fan and outside fans are required. We also carry numerous window insulated window coverings as they do help. Currently looking for a pillow for our front vent. We also invested in the awning shade insert cover and even purchased an additional shade screen to go over it, as when parked in direct sun the blue shade cover is not enough. We love camping and being outside when possible and these extra conforts are a must! :)
