One mans meat is another mans poison.
Covering the vents on our Fiat Auto-Trail makes a big difference with our Taylormade external cover.
Must say, I never thought of switching to recirculate though.
I'll have to go outside now and give it a try :thumb:.
Thanks for that tip
Well I guess Ducato cabs might vary a bit depending on what the motorhome manufacturer might do with them. I have played around with my Hobby/Ducato quite a bit (if in doubt I will fiddle ) and with the heater on recirculate, covering those top vents made no difference.
