Tongue Jack Help/Recommendations

Well l learned something interesting today. Apparently all of the Atwood jacks use the same motor, or at least the Standard, Deluxe and Heavy Duty do. The difference between the Standard and Deluxe, both rated for 2500# is simply the addition of a light on the Deluxe. The Heavy Duty, rated for 3500#, just has a different mechanism in the shaft (ball & screw). I expected it to be a higher capacity motor as well. Nope.

The motor is being replaced under warranty. Also discussing with the RV dealer about upgrading to a 4500# Husky jack.
