I can not answer your complete question on that but the compressor's SECOP ( formally Danfoss ) have been around for years. In the years that I worked refrigeration I never had to replace many Danfoss compressors. They were/are used by Mercedes etc. Now there is a newer plant in China but are still made in Europe. It is good that there is US based support. But for what it's worth ICECO is on my buy list hopefully yet this month, not saying that Dometic or ARB are not good units as they very much are but when you have a limited income ( retirement ) the ICECO price point looks good to me along with the reviews I have read and looked at. Hope this helps as not confusing. Good adventures to you folks, travel safe
