Can 4,000 lb PowerBuilt Unijack be Used with 5,000 lb Trailer

Question

Question:

I want to purchase a UniJack, either Item # ALL620471 or Item # ALL620470. The application is a 5000 lbs dual axel travel trailer. Is the 2-ton adequate? I prefer the 3-ton but am concerned about the height of the 3-ton jack not clearing the axles which have just under 10 inches of clearance. thanks
