Thanks for reaching out, Dennis!

I recommend going with the 230 lb capacity Conventional Ramp Door Spring for 8' Wide Enclosed Trailer # 362SA8HD for your application. Although I don't know the exact weight of your trailer door, according to my research your door should weigh in somewhere a little over 200 lbs so this ensures that most (if not all) of the weight of your door can be handled by the spring.
