I have a Itasca with this frig Dometic 2401.. And its not cooling . it only makes a guggling noise .. My question is If I buy a new frig and install it myself .. would the company stand behind the warrentty ? I read Norcold have 5500ft problem the Dometic we have never had this problem .. So Looks like I'm shopping for a Dometic.. wheres a good site to buy this new spendy unit ? any help be great. Units about 17 years old and 100,000 + miles.. this a great forum . wish I knew it was here 15 years ago ... ..
