Well I guess I’ll jump in with some very positive aspects of Cornerstone. We have a 2018 Newmar coach (with 48,000 miles)and after the one year factory warranty Cornerstone has reimbursed over $13,000 in repairs/replacements to awnings motors, residential fridge repairs, rim replacement, and HVAC repairs….no hassles, no disputes nothing but outstanding service…..self insurance concept is questionable. I enjoy the lifestyle and the peace of mind…
