Fulton 1413230134 F2 Marine Trailer Jack - 2000 lbs Capacity, Sidewind Bolt-On Mount, 10" Travel - Perfect for Boat Trailers & RV Camping

Top quality, very stable, so much nicer than what came with the trailer, worth every penny. I don't miss having a wheel because the boat/trailer was always too heavy to move around by hand anyway. Tip: install this jack while your trailer is connected to your vehicle so you can adjust the height of the jack for adequate swing clearance to the horizontal position. The instructions do mention that you must remove the jack to adjust the height. Once mounted, you don't have access to the two bolts that must be loosened to adjust the height. Also, you have to remove the main pivot bolt to get access to the the other bolt that must be loosened to allow it to slide. I initially installed mine while the trailer was disconnected from my truck. When I connected the trailer to my truck the jack did not have enough ground clearance to swing up and into the horizontal storage position after the weight of the boat compressed the springs on the rear of my truck. I had to remove the jack to make the adjustment.
