I have a Mallard 335 that I bought new in July of 2021. Five months into ownership, the main air conditioner failed (GE 13.5K BTU). After the lengthy process of the warranty claim through Camping World, the unit was replaced with the same size and model. Well, five months after the new unit was installed, it has failed. I reached out to Heartland to see if I could replace the GE with another brand. The short answer was no because it was the vendor, GE, who warranted the product. I reached out to GE and found out that their units are distributed by a group called Midwest Sales and Service. I emailed them and got a response the very next day. Their units are warranted for 2 years (Camping World avoided telling me, but I should have known) and the gentleman at MWSS is working to get a mobile tech to install a new one so I don't have to deal with Camping World again. The problem of the GE air conditioners isn't really solved and I won't really trust a new one but if I continue to get replacements, I'll go down that road. Has anybody else had problems with GE A/Cs?
