I ride the Backou Mule, it may be a good fit for you. Hardtail, not full suspension like the Storm. If I was towing a trailer, I think I'd rather have a hardtail, as the extra weight of the trailer may do strange things with the rear suspension ... The Mule is solid. No problems, after 6 months of riding. The standard battery (~17 amp hours) has a realistic range for me of between 14 and 22 miles, depending on terrain, in ECO mode level 1-3. With a trailer you'd probably be on the throttle and maybe in Sport mode, so your range would be less. You'd probably want a spare battery.
