I just purchased my first HD, a 2005 Ultra Classic with only 13,500 miles on is . I do live in Arizona so I felt the bike would benefit from the use of a cooler… Glad I found “Ultra Cool”, Nice guys to deal with; I ordered the wrong cooler. I spoke with Earl arrangements were made for the exchange, no hassle! They waived the shipping charge on the initial purchase. Now its on the bike and working. I think they named the product after Earl “Ultra Cool”
