Van build parts resell - Dometic AC

hi there van life fam, first time posting to the forum here. Im curious if anyone know of any place to resell van life parts and pieces. I purchased a Dometic AC a few moths ago and i have decided against using the interior mounting kit, $299 value brand new… Im considering going in a different direction with my ac unit choice for space saving reasons and i may want to sell the whole unit all together, i thought about using facebook marketplace, but i feel like there must be a better place for the re-sell of van life products, can anyone point me in the right direction???

How much is complete unit?

hello, i payed $3,097.99 for the unit as well as the wiring kit and installation hardware kit. are you interested?

oh okay, it is pretty high and out of my budget. Thank you thou!
