Installed KOOLRVs

I installed KOOLRVs in both ACs in my DynaQuest XL 3801TS.

The installations were pretty easy. Most of the time was spent using foil tape to make sure there were no air leaks.

They did provide a bit more air flow in various outlets, but I’ll wait to see if they actually help keep the coach cooler.

I had looked at these and was curious how they performed. Thanks for the post!

Man I wish I had known about this 2 years ago. I went with the RV Airflow inserts but for what they air, it was definitely pricy. But I will admit it did make a difference. The KOOL RV setup looks like it would have done just as well at a much more economical price.

First Iíve heard of the Kool RVs. Iíve bought two sets of the others. I just hope it comes back from the factory with them still installed after they put a new roof on it. Let us know how they perform.

It would be interesting to know the cool down time with and without these.

use some insulating material around it
may/might cut down on some of the noise


don't use spray foam ...
get some scraps of upholstery foam from a local upholsterer..

I have the RV Air Flow and I can say one side effect in our XL is a squeaking sounds from the styrofoam on the road. I have a Kool RV on order to see if that fixes the issue. We shall see.

If they are squeaking Iíd think the a/c was loose. I havenít noticed any abnormal squeaks in either rig weíve installed them in. Canít wait to see if it corrects it.

AC is torqued down properly. The styrofoam was a really tight fit, and it is that odd noise that foam makes, so we hit certain bumps, some that kind of twist the motorhome, that is when it squeaks. I know the squeak wasnt there before I installed it.

Strange, I installed the RV Airflow units in ours after we talked at the Rally and have no squeaks at all. Ours were an extremely tight fit, too. I did tape them up pretty good as well. The tape around the edges seemed to quiet them down even more.

I was not pleased with the fit, it didnt go all the way up at the back side, so I am thinking it is rubbing on the metal plate.

I have mine on pre order for September delivery. I made my own with styrofoam on my last MBS and it made a HUGE difference.

Iím hoping this new version will do the same on this MBS.

Will be interested to hear if you post an updateÖ

KOOLRVS

Just installed 3 weeks ago and happy with the results.
Pretty tough to tape around the duct connections so I cut small dowels to make a snug fit to hold fittings in place and used low expansion foam.
So far so good!

Built my own at a fraction of the cost

I built my AC diverter box for our main AC in our 2015 Nitro XLR from green insulating board from Lowes. I followed directions from several YouTube videos. Total cost of board and aluminum tape was approximately $10.00. I also added a couple of small air dams, made from strips of scrap cardboard and covered with aluminum tape, to help divert some the increased airflow to the main cabin. The increased airflow was forcing the increased air volume to last vent in the garage. The mod increased the airflow tremendously and it decreased the cooling time by 60% by my calculations. It also decreased the noise in the main cabin by +80%. You can have a normal conversation now in the main cabin. I'm not sure why these new AC diverter mods are so expensive. I would think even a 3D printed unit would be cheaper. Since doing this mod, I haven't had to use the front bedroom AC much at all. Running it usually helps cool things down quicker and then we turn it off. All you need is the foam board, aluminum tape, tape measure, straight edge or square, and a jig saw. Took me about three to four hours to build.

Will it cut down on the noise from the AC unit?

corky310, It reduced the noise tremendously!!! You can actually have a normal conversation without yelling and watch TV normally.
