Ron The 500 hour requirement with Avemco might be a little soft. A rep at Oshkosh told me because I have a construction policy with them, they would probably cover me at 300 hours. Previous to Avemco, (3 years ago) I had a policy with U.S. Specialty Insurance Co. through "Rollins Hudig Hall" Wichita Kansas. 800-835-2677. These folks were good to work with and knowledgeable.
