I guess there was a few considerations before I decided to do this. I'll start by saying that this camper is perfect for us .
And adding in personal details now is mostly for comfort.
After doing some dry camping last year it was the 1st thing I noticed that I wish came with our unit.
I feel every camper should come standard with a range hood, n i dint really consider it on my checklist originally untill we started using it.
However , I never ran the bthrm fan before during cooking, nor would I suggest it, it just seems unsanitary, you might be pulling fumes from your black tank into the air.
Anyhow, for now start with a small fan by the kitchen window , i had a ryobi cordless fan that I used , but If your a do it yourselfer and feel like it's necessary, then I'd say go for it.
I'll tell you it took me about 10 hours to install, i just wanna add I'm not like crazy perfectionist, I just make sure its done right.
I incorporated some extra Detail to help the longevity of this kind of install, so that's why I took most of my Saturday to get it done .
I also think if you feel uncomfortable cutting into your wall then it would be a good idea to ask your rv dealer about this kind of installation.
I'm sure they can handle it as well. Anyhow , hope the feedback helps in your decision.
