Air Con. question

Can someone give me a little comparisons to go on. I have a 38 GK with 2 roof airs. I was assured by the dealer that I would be cutting back on the AC. Well I am in south Louisiana. And it has not yet got as hot as it gets down here. Both airs are running wide open. And according to my t-stats 75 is a cold as they are getting. They ran most of the night. shut off early this morning and cycled until about 7:30 am. But now they have been running all day long. Does anyone on the forum have 3 AC units? if so is it set up to run through the existing ductwork or is it one that just dumps the air? This was one of my concerns when I bout the RW. Folks up north just don't understand what Hot and humid South Louisiana and South Texas weather is really like.

I have a 38GK as well. What I have done when it has been really hot, is a form of manual "zone" control. During the day, I'll close the bedroom vents and even at times, the 2 vents in the hall, thus forcing all of the cool air into the living space. We don't have hot nights, but if so, I would reverse the procedure closing some (but not all) of the living room vents and forcing more air to the hall and bedroom.


I close both the bedroom and hall doors when doing this. Also check your air filters, mine sure get dirty!

I have a 36RL and temps have been 97-108 the past two weeks. Best my coach does during the day with both a/c's running wide open is 78 inside. We do not have any trees around the coach to provide shade, but I am a bit surprised that 78 is the best the inside will get until the sun goes down.

These supposed full time units are not insulated as well as they should be
You can hear your neighbors or people talking in the trailer when outside. The slides have very little sound proofing eg insulation. I have had numerous trailers over the years that did a way better job of retaining heat or air

I agree.

I had my 36RL in AZ during June one year without a problem but we did use a tower fan to keep the air moving.

Keep all your vents closed because the a/c units will draw in warm air through them. Also make sure your cargo doors are kept shut. In the 36RL the front closet got very hot but I found that if I kept the doors open, the heat would not build up as much. A couple times a year get on your roof and spray off the fins of the A/C unit to remove dirt and debris. We also kept the shiny bubble insulation stuff on the bedroom windows because we sleep with it very dark and cold (67 degrees).

We use a couple of oscillator fans, ceiling fan, & be sure to cover the shower skylight & stay very cool.

AC's not cooling ?

I am in Arizona and have had many very warm days 100+. I have a 2012 36RL Redwood (For sale by the way). I have never had a problem cooling of the rig. However as Dave has said you may need to block the heater vents. Close them if you can on yours and if you cannot buy new ones. What I also did was to block what I will call the heater return area under the cabinet area located to your right as you enter your rig. There is a large area on the bottom covered by a screen in mine so I made a nice piece of wood and hold it on with Velcro so it can be removed. I believe the two AC's running suck a lot of hot outside air in and dust with it. Also have double pane windows but I guess they all have that. Also make sure AC fans are on high.

We full-time in our 36FL and are from the Dallas/Ft Worth area. We have been I that area when temps are high 90's low 100's. When we are not travelling in a cooler location, and have to be in the hot weather, it is difficult to keep the unit cool. However, we do/have done the following to help. First we completely closed off the bathroom skylight with bubble wrap insulation. We also keep the window shades closed, and also manually adjust the cooling vents to maximize cooling in the different locations in the unit. We also make sure that the filters are kept clean...sometimes we have to clean them almost once a week. By taking the steps, we stay pretty comfortable even in the hottest time. Also, finding a shaded area for the unit helps considerably.

Has anyone installed a 3rd AC unit. I have not checked power requirements but seems it would be worth the money.
