Ive been using these for a few years now, abused them and they've never let me down.
Best thing about them is they double up as traction aid, are lifetime warrantied, they are rated for 50k lbs and are made in Canada amd USA (so prices on their site may be in $ cdn)
I have the XL ones (longer), everyone i showed them to emded up buying a set as well
The site may not show it but when stacked they act as leveling blocks...
I don't have a pictures with my van but check them out on this link, you won't regret it!
Cheers
David
