A warranty is only worth the longevity of the builder. Ford, GM, Ram, all good we are sure they will sutvive. Rambler, AMC might have got a buy when Chrysler bought them but Saturn warranties are gone. Maybe GM still backs Olds warranties but anyone building trailers in back water USA...... you want a warranty???? Sure I'll offer a 40 year warranty on what I build and in 3 years when the lawsuits arrive.... Chapter 11 and I am gone. I'll just change names and keep building.
A trailer warranty is nothing like a car. If the trailer hitch still couples and the wheel bearings still turn.... all is good. On components like heaters cooler doors windows.... those are all under manufacturers warranties, nothing to do with the builders.
Define the difference between 5 year and lifetime................ Pay atention to warranty lol.... no pay attention to how long have they been building trailers. pay attention to 1M satisfied customers for 100 years...., ie Airstream vs..... 14 positive reviews on facebook..... ie all the rest. If you buy that state of the art $50K tear drop trailer you are paying for image, status, ego,,,,, just like buying a 1960s sports car called a Cheetah or ..........
There is no warranty on any expo, tear drop, nubu trailer. Warranty is all about brand name established manufacturers.... even then they setup separate entities to avoid the liability. You have a warranty claim..... you will spend exponentially on legal fees to get it resolved and before that happens the manufacturer will change names and market a new brand.
Warranty in the RV world is buyer beware.
Even things the manufacturer builds like the frame. Our legal system offers so many outs he'll claim the steel from China was not to spec. And he's free.
Yes we pay attention and when the warranty looks to good to be true..... we walk.
When I buy a used car I like a 12 month warranty. First I'm sure you will be here in 12 months, second if it lasts 12 months I'm kind of comfortable it'll last 12 years. A lot of dealership used cars come with 12 month warranties which is why I buy used thru dealerships. I know they did a full mechanical check because they don't want a warranty claim and they want o be known as a premium used car dealer. Over the past 30 years I have bought 12 vehicles that way and never been burned.
On trailers, no warranty is more valuable than due diligence. Look at the reviews. Set aside yer ego. Forget the stupid reasons you want it. Go home. Talk to the wife, Dad, Son, get other input..... and buy it tomorrow. Warranties on anything "custom manufactured" are worthless.
