our 2024 Avenue 32rls has the two vents coming out of the island and I basically covered the one that aims towards the oven and stove area. so the air that goes into the box will blow out towards the dinette set and recliners and it actually blows a lot harder. I have heard people have completely removed vent ductwork and ran it straight out of the island on the dinette and recliner side. I've also insulated the box in the island with thermal foil tape so that it does not lose or dissipate heat and warm up the inside of the island. also found that there is no covering on the bottom of the island so when the air blows out it basically just fills up inside the island and warms it up. I was able to cover The underside of the island so when the air comes out it just doesn't go up. it hits the flat part that I installed under the island and blows straight out onto your feet. hope this is not too confusing. The first photo is the vent that aims outward towards the dinette and the recliners without the cover I installed. as you can see that is the underside of the island and all the hot air just basically goes into the island when it blows out that vent. second photo is a cover I installed so that the air that comes out of the vent blows straight out and not up into the island. Don't know if this helps but I think it does for us at least.
