I used this business recently while between apartments. I compared their rates at the time with two or three other self-storage places. Sentry's was the best in town. My 10'x30' unit had a roll-up door on each end and no leaks or weather penetration to report. My unit had no light built in, however, the facility itself is well-lit (and I recommend a cordless lantern or flashlight in both your car and storage unit regardless). The 10'x20' units are single-door. I also used their outdoor parking, ideal for recreational vehicles or unhitched trailers. They have a variety of units on site. Some appear as small as walk-in lockers, and I understood there are bigger units for RVs. The only qualms I can think of are the access gate hours. It begins as early as 0700 but 2100 wasn't late enough for me personally due to my schedule when I strolled in from out of town. Friendly people above all. I would recommend this business to a friend or family.
