well, I received my hawk week before thanksgiving. and took her out for 3 days and 2 nights. that trip was cold. so I added reflectrix and a way better sleeping bag and blanket. last week was her first big test. Mon-sat 6 days and 5 nights at king of the hammers out in the Johnson valley desert. weather was great. warm days, and the nights weren't bad due to a cloud canopy at night keeping the days heat down low. the hawk provided a great place to prep meals, sleep, have morning coffee and a restroom. with 2 agm batteries and only using lights, and occasional inverter I never had to pull out the solar panel. I wish I did though. just to top off and test out. used the heater only on the first night. due to some wind. racing action was at its best. and pulling my utv on a trailer with the hawk was not an issue. will post pics when I can.
