Sleeping cool without AC

Our past weekend trip in Central Oregon left my wife asking for AC, something I dread. We've avoided hookups and generators for 15 years, and I'm not very eager to start now. Nearly naked on top of the sleeping bags, windows open, FF on; we'd sweat until temperatures finally dropped in the morning. I note that there are several mattress toppers on the market that claim to have cooling properties. Can anyone vouch for any of them? We've been using a dense memory foam topper that makes our bed nearly as comfortable as our Tempurpedic at home. Maybe this is part of the problem; but with a sheet and two layers of sleeping bag on top? Any suggestions for staying cool and AC free? Thanks.

  • I think the OP is referring to gel-infused memory foam. It claims to wick away body heat rather than hold it all in like regular memory foam does. I have been thinking of trying it also. Hopefully someone here has this stuff and can tell us how it does?

    (edit: I read some reviews for these gel-infused toppers, and most of the reviewers who had regular memory foam before the gel one say that the gel does keep them noticeably cooler.)
  • A/C not only cools by blowing refrigerated air, but also dries the air. It has been down in the 50's for the past week here in NW Arkansas and low humidity - but as the old saying goes, If you don't like the Arkansas weather, stick around, it will change. It is hot and humid today.
  • Been there, not much to offer - we too refuse to do an A/C & everything that goes with it - watch the micro weather forecasts & get above 9000' on the hot days.
  • Memory foam or any foam does make it worse. Go to higher elevations to camp, near cold rivers, or stay up later.
  • A soft mattress (this includes whatever is on top of it) has you sinking in and trapping heat.

    We just use a regular sheet over the mattress in hot weather. This won't make a huge difference, but might help.
  • Was at Misery Campground last week (Blue Mtns) over 4,000 ft.

    Not bad at that altitude.

    Cutting wood during the day helps with sleep.
  • FF fan is great as it runs on 12v with very low amp draw. Try opening either the pass thru window or just your bedroom windows with the fan on exhaust...this will draw cool air in...
    Don't open all the windows! Just the "critical" ones near you...

    We don't use AC either...didn't even order one with the new EC.

  • I'm guessing that "FF" means "Fantastic Fan," as in the bathroom vent fan.

    I just blew $75 ($65 + $10 S&H) on a 12 inch 12 volt fan from CW that claims to move 900 cubic feet of air a minute in comparison to our Fantastic Vortex bathroom vent fan, which moves a whopping 188 cubic feet of air a minute, both for the same 3 amp draw.

    Says here it puts out a 10 mph breeze.

    I ordered it because two weeks ago we camped at a campground we love, but at which there is no electricity. There was also no breeze whatever, and thus no air movement through the camper. We did spend the night naked on top of the covers. It got mighty flippin' hot!

    I don't yet have that fan, so we haven't had a chance to test it out. But I'm thinking that the 12 volt receptacle on our TV shelf is close enough to the window next to the bed, . . . .
  • Two bottles of water with spray nozzles, you soak each other, the bed, and then let it evaporate and cool you off.

    Get a couple of used computer fans and build a mount for them. They draw only a tiny amount of power and if you can mount them on a flexible wand to aim them where you need them, they help too.
  • We don't full time but when it's to cold we go south and when it's to hot we go north.
