Fantastic Fan Installs... any words of wisdom?

Someone also makes an insert like a fantastic fan that fits into your existing vent. Probably not quite as nice but much cheaper and you do not have to take out the old vent. You just take out the inside guts and replace.

I did one on Tuesday, used butyl tape instead of that foam junk. Easy peasy, just keep the hinge facing the front of your rig. Cutting the dumb trim ring was by far the hardest part, a jigsaw would have been nice.

Otherwise it's very straight forward but I would not use the cheesy foam gasket that comes with it. it's just one more thing to fail.
Mine have been in nearly 10 years and have worked great and never leaked.

Should I use the putty tape stuff? any recommendations?

Pretty straightforward mod with removal of old sealant the most tasking part of the process. Just take your time with that phase and don't fret if you don't get every bit of the old sealant off. I installed a couple (bedroom & main room) of vent fans and 4 vent covers just after purchasing our TT 6 years ago and they have been performing well.
