Even a strong AC system that's powered with the right amount of amps can use a little help.
"We have a good AC in our camper, but we still like to make use of a small portable fan while sleeping to minimize the noise from the A.C.," says Grant Sinclair who, along with his wife, runs the blog Our Wander-Filled Life, which documents their time on the road with their travel trailer. "When boondocking, we have a battery-powered fan from Ryobi, which uses the same batteries as our drill and other tools, to keep cool on hot nights."
You're not, however, confined to a specific brand or style — and when it comes to the number of fans, more is almost always better.
"There are also countless portable and mountable fan options available," says Luca Sumberac, category manager at RV parts and accessories supplier CAMPERiD.com. "Strategically placing a few of these within your rig will keep the air circulating and your passengers happy."
