Coolng RV

Setting a dehumidifier in the shower to drain seems to really be effective in a 34' Southwind;

We have been having fun with keeping our 87 bounder comfortable in this 100+ constant southeast tx weather. Been especially hard with our 1 remaining roof a/c finally dying of heat and old age.

With a replacement roof unit out of the equation we opted for an 11k btu portable lg a/c vented through the front passenger window. Our spot is pretty much in the sun all day with the front windshield area getting the heat during the hottest part of the day.

We have black out drapes replacing the original front drapes which help. Two fans help circulate the cold air from the a/c but it gets pretty darn hot inside during that high of the day. So we have reflectix ready to go up inside the windshield and other windows.

Final solution could be household roof insulation board that has the foil face one side,put inside various window frames. Only other way is to go outside and go in the littleones paddling pool!! Or visit a store with cold a/c!!!!!!

This summer is just a real bad one so early on here so having to improve our strategy as we go.

geekyexplore......If you were connected to 30 amp power, you never had both A/C's running. You may have heard the fans on (they'll continue to run) but your power management system was only allowing one to run at a time.

If you have a 50 amp coach and a 50 amp connection, you'll get both running at the same time.

I added a roof unit to my basement air. Cool in Texas summer is no longer a problem.

You really have to manage the heat BEFORE it comes inside the coach.

The windshield is just a giant solar collector; the silver Reflectix works the best here, backed up by your lined windshield drapes.

If you just can't stand this idea, purchase sunshades, like Magnashades or another good quality brand. You will still be able to see out and it will kill a lot of the sun.

You can also put a reflective window tint on your side windows (not in the cockpit). Again, you'll be able to see out but it will cut a lot of heat.

Cut a piece of foam to fit inside your skylights- these let in an amazing amount of heat.

Use floor fans (Fantastic makes an excellent 12 volt fan called the Endless Breeze) to keep the air moving. The human body perceives moving air as a drop in temperature.

Keep the awnings out and hang a sunshade on the awning rail if there is glare off the concrete that bounces back to the coach.

You'll make your tin box a lot more comfortable these hot summer days!

Funny you should mention magna shades Senior Chief, recently got a quote for the windshield on our bounder. Although a good price just a little bit steep right now so got some reflectix ready to go in the windshield,as it seems to be the next best thing to a tailored shade.

Also have some of the side windows already tinted along with cheap copy reflectix shades which do a fair job. Armed with the proper stuff every panel we can cover won't be safe!!

Putting the reflectix on the OUTSIDE of the windows improves it's performance.

I know it seems like there should be no difference between inside and outside placement, but trust this old, fat, and ugly retired Navy Chief - - it does!

Thanks for more input!

We were debating on a dehumidifier - that probably does help take a lot of the stickiness out of the air.

We have the ability to get into cool air via or a store or something - but our animals don't so that is another reason for the concern.

Diplomat Don - yes - I didn't mention that but we are aware it cycles between the two. We are all too familiar already with 'shed'. Another reason to upgrade if we really decide this lifestyle is for us fulltime. We are still glad we got an RV in our price range (and it's a nice, nice coach) but we are thinking 50 amp diesel if we can work out the balance between contracts & traveling. That decision is still a year out however!

Thanks for the Magnashades info - we will check that out! And keith was doing some research and window tint might work out as well.

We have basement air and it can usually keep up just fine. Keep in mind that an RV is a big metal box. A few things that help are.
1. Park in shade as much as possible.
2. Run fans but only inside fans, never vent fans with the AC on.
3. Your AC is refrigerated air, make sure that no windows, vents, or doors are open as refrigerated air needs a closed system to work.
4. Have the awnings out to shade windows and the big metal side of your RV.(except when driving lol).
5. Pull the shades and in the big front window put up some kind of reflective insulating window shade, we use a big silver one that goes in front of the drapes. You can also insulate side windows, we do in the winter.
6. Cook outside on the grill or eat out.

Using these tricks we can keep our RV comfortable in 110 deg. weather here in the Southwest.

When we first got our RV it had a bunch of cardboard window shields, my Wife put them in all the windows. When I went outside i noticed that all of them said in big letters "Need Help Call Police".
An RV'r is someone driving a $300,000.00 Motorhome towing a $40,000.00 car and looking for a free place to park.

Didn't see following mentioned.
1. Leave slides in for less space to cool
2. Insulated ceiling to floor drapes just behind cockpit seats, again less space to cool
3. Convert to led lighting, less heat generated inside

4. We drive north

we removed our shades when we bought our class c replaced them with curtains the wife made by cutting down eclipse home curtains from wally world they have a backing that reflects the heat and still looks like normal curtains,and we made a set too block off our upper bunk during the day and another set to block off the cab at night since we did this we can cool our coach just fine before it was a struggle.
also i cleaned the coils and filters on the unit that helps too.

just my 2 cents worth
