Camco's RV Adjustable Stabilizer can be used under the front or rear of the trailer for greater stability. It has a large reinforced base for better ground contact and has a 5,000 lb capacity. This trailer stabilizer adjusts from 9" to 14" to meet your specific needs. Easy to put in place, it can provide the added security of a solid lift. Durable and made for regular use, the lift is a nice accessory for practically any camper or trailer owner. The stands can handle most trailer weights, making them stronger than many other similar models available today.
