Yeah, I'm hearing "We've had it since 2009/2010 and haven't had problems." Unfortunately, that's not a very long track record. I see old Tetons out there and other known quality manufacturers from the early 90s with no problems with shorter slides, but nothing that old even exists with these 30+ foot slides. I'm wondering what those super long slide units are going to be like when they are 15 years old. I'd probably trust Newmar since they are doing it in their really expensive Class A motorhomes. I wonder if Carriage/Lifestyle and some of the other "upper mid priced" brands are doing it well enough. Only time will tell, I suppose.
