Ac not cutting it

Is there a 2nd AC unit available for my Rockwood Windjammer 3008W? The bedroom is too hot! This is not a cheap unit and I think with the money we bought it for, it should be working properly.

You should be able to install a 2nd A/C in the bedroom. I'm not familiar with your RV, however, it's not unusual to need 2 A/C's in the larger sized RV's.

We have a 3006wk with only one 15k AC and it is not enough for this East Coast heat. It worked fine in CA but I think the humidity along with the 95+ temps is too much. We put Reflextix in most of the windows and that helps but the only thing that really helps is getting it in shade. I am thinking about adding a 2nd AC in the bedroom also or possibly a portable unit and create a vent to the outside. There have been some recent and old threads on "pimpin" the AC and expanding the ducting that I want to try first. Just need to wait till the weather cools off enough to do it...

Might not be the a/c so much as the trailer/RV itself. It was the case with mine.

Have a look here...

Does your unit have 30A or 50A service? If 50A should not be too much trouble to add a second AC unit.

Thankfully we ordered ours with the 15000 btu unit. I'm not familiar with your unit but is it ducted into the bedroom? If so try shutting the grates on the a/c in the main room and directing more cold air into your bedroom. We have had some very warm and humid nights this summer in Illinois and when we redirect the vents we sleep comfortably with blankets on with the ac set at 71. Our TT is 35' long.

Yes, we have done all that you have said. Ours is a 35 footer too. We have talked to several people and they say hot is hot. We were at my dads when it was 131! Yuck! We won't be going there in our TT in the summer anymore. Lol we too have the 15,000 BTU unit. Look into getting a 2nd unit but it would have to be converted to a 50 amp. Some campgrounds don't have that available. We just decided to get a good oscillating fan when we sleep and it can suck the cool air from the living room to the bedroom. Sigh.

I just got done "Pimping" the a/c in our 2504s. While I was there I added a hard start capicator. Instead of just glueing the insulation on I also used silver metal tape that is used on ductwork in houses. Seems to cool a little better and start up easier. Plugged into a 20 amp line at our house I couldn't tell when the compressor kicked on. No bog at all. I would try this first before Putting in a 2nd unit. I am also going to block off the ductwork that is unused at each end. Does anyone know how those round vents come down from the roof on the inside if the camper? Jay

AC is probably fine, 1-15k unit for a 35' TT is just not enough. How do I know? Been there done that.

Converting a 30A to 50A is a pain and could be quite expensive. Most economical option is to install 2nd unit and run a separate power cord to the campground power pedestal.
