We have them on our QS10 and have had good luck with them. We don't have AC and the gizmos do help cool things off a little. The biggest thing we like is that it makes it a little darker in the morning when we try to sleep in a little bit. There is no really easy way to put them on the camper and we are still experimenting with a couple different methods. When we camped at the beach last summer with no trees in the campground we noticed a big difference with the gizmos in place. The other benefit is in the wooded areas with the gizmos keeping the tent clean from leaves and tree sap.
