Ditch it. Airstream warrents everything for 2 years which gets well past the infant mortality on everything.
When you buy a warrenty, you are paying 2 profits above the likely repair costs over that period ... the seller's profit and the warrenty company's profit.
Month after month the letters to the RV magazines are full of folks who found out that the warrenties were a disappointment wrapped in red tape.
