Has anyone tried this yet? https://koolrv.com/ Seems like it could be a better option than the RV Airflow and definitely easier to install, but I'm always hesitate to try something that hasn't been on the market very long.

Just got the one for Coleman mach last week, very easy installation. The last step of installation says before reinstalling cover turn ac on and feel around for any cold air escaping and use provided tape to seal any leaks, I had no leaks and just looking at it can't see how it can't be much better. Of course after I installed the temps in pa. have cooled some but 90s next week. My airflow numbers at some ceiling vents dropped a little, doesn't make sense, but air temperature at all vents dropped considerably. For the price I'll be ordering another one for my other ac.

But what if you want to occasionally use "dump mode" for a quick cool off? Looks like it eliminates that?

It does but in 5 years of full-time really never used it.

Yep, eliminates that feature. We use it all the time, especially after first arriving and fighting the residual engine/exhaust heat up front.

I just installed the unit in my Coleman AC.
Easy install up to the install of the two "vent adapters" that they state that the vent openings may be larger than the adapters.
WELL, that was an under statement. Openings are considerably larger! Gap on bottom and one side are damn near ½".
I solved that issue by 1) Removing the 2 rear bolts that secure the AC, and 2) place a strip on foil tape on top of adapter 1st, then placing it top & rearward.
After thoroughly sealing all 4 sides extremely well, I replaced the 2 rear bolts tightly.
Other than the gaping, far from correct size, adapters, install was a breeze.

(FWIW, they say to save the "chute" and the foam divider in case you want to revert upon sale of RV. No way would I want to go through that---I tossed them in the recycle bin!)

There is another one that reduces noise and increases air flow. I installed that one and it works well, but cost a lot more. One AC. front, works up to 96 degree out side now. Over that we turn on the rear one. Prior the front AC provided almost no flow through the rear vents. After the install, there is a lot of air flow in the rear and strong air flow in the front and middle vents. If I had to do it over again I would, but use the fix below. So long as you do not have a problem with noise, the product listed above is great. That rear AC was so loud you could not hear yourself think. So long as you have blue insulation board around with metal tape, you can do the same thing. Several post on this that I did not know about.

That video is quite similar to the KoolRV in principal, but far more labor intensive!
I'd gladly pay the $79.95 again rather than have to go through that hack.

And by removing the center divider you double the air intake.

Nice $80 we may try

i tryed the kool rv the openings in the coach were much bigger
then the adepters on the device. i sent it back and made my own. not to hard but i have the time and looking for something to do.

Yes, as I said above, the gaps are considerable, but the tape filled them in well.
Just start with the top rear corner and fill in the other sides.

I think most of our issue was ducting. The duct works is just styrofoam boards in the ceiling. Lots of gaps. I think you just block off the ducts and use the dumps. I installed the rv airflow (custom piece of styrofoam). It added some air flow but not enough for one 13.5 btu unit. So I replaced the front vent with a nonducted 13.5. It alone will cool us in temps up to 90 with no shade. I also saw several new 2024 units at the Charlotte RV show using non ducted units even in large luxury 5ers.
