MrsHuskyHog,
You are not alone in your issues with the unducted A/C in the Bambi. It was a major factor in our decision to upgrade to the Flying Cloud.
I googled the topic of RV air conditioner noise reduction and found one company that offers a quieter A/C that is a direct replacement, so there is a company out there that recognizes the need. (Please do your own checking - I don't want to appear to endorse something I have no experience with.)
This topic received extensive coverage about two years ago. No one on the forum had a straightforward solution, other than to buy a
Caravel to start with. Sorry I don't have more to offer.
