We will stock parts as required for our customers for as long as we can. By the time we even come close to running out of parts, Truma NA will have seen the light at the end of the tunnel and will start selling to the aftermarket.The other question to ask, is are spare parts available? When/if the unit needs service, having a stateside source will be important, as will having a factory service manual or similar. I doubt you will find many dealers/shops/RV service locations that are familiar with this unit, and even fewer who stock parts.
