I used what looks like the same ones although I got about 2 years out of them. I have a Compass which has dual rear tires and weighs about 11,000 pounds, so I had four of them. I have since purchased the one in the link from Amazon, and they seem much more durable. At the same link, I now see they also have a Super Leveler which is rated for 10,000 lbs while the ones I have are rated for 4,000 lbs.
Camco Yellow Drive On Tri-Leveler, Raises Your RV Up by 3-7/8" Works on Any Tire , Has Built In Handle, Load Capacity of 4000 lbs, Durable Non Slip Surface (44573) https://www.amazon.com/dp/B000BUQOFO/ref=cm_sw_r_fm_taa_ovD2CbW7VSWRN
