I had my Elkridge E293 for less than a year and recently during the rains, we have discovered a leak. Heartland will not warranty the defect, even though it's visible they missed the corner. They claim that the warranty says you have to inspect the unit every 90 days. I have had a Kit Companion trailer for over 25 years and have never had a leak (let alone the first year), so I am kicking myself for not reading the manual more thoroughly and expecting a better product. Has anyone had any issues with their warranty? what recourse do I have?
