After a year of listening to the power jack on “The Baby” sound like it was on the verge of parting company with its inner works I decided an upgrade was in order . A trip to our local RV shop to winterize “The Baby” also lead to a discussion regarding the jack. I lucked out in that they had a model in stock that had been ordered but not picked up and were willing to sell it to me at the old price. This meant I was able to purchase a heavy duty 4000 lb. power jack for less than I could of bought the upgraded version for the trailer.
