I installed the Husky Brut 3000, and it failed completely after about 5x. There is a small shear pin in the top motor housing that failed. We were very careful NOT to over extend the jack. After raising the camper one time to about 3 inches above the TV ball, while pulling the TV forward the jack completely collapsed (also bending the front stabalizer jacks somewhat) We were in a very remote area of WY and had to drive over 100 miles to a RV dealer to purchase a manual jack. Once the shear pin fails, there is no way to repair the jack in the field. All of the gear housing a supports come apart if you try to remove the motor housing.
We got a partial refund when we returned from our vacation and went with the Barker 3000. My RV dealer said they had a few Husky jack failures.
