is it 4 yrs AFTER the 2 yr warranty? or 2 years after the 2 year warranty? the trailer includes a 2 yr warranty. also find out what kind of coating. they are already clear-coated; i'd be curious to know what they are trying to upsell you. An additional 4 yrs after the 2 year included warranty might be worth it; read the forums and see what kind of problems new trailers have.
then again, a warranty wouldnt cover much of these problems; filoform, shrinking / expanding vinyl floor covering, rusty rivets. what else am i missing?
