04 Argo Avenger with 18" super tracks tracks plus extensions sitting at 7' wide.
A foot print of 2300 square inches per side and about .5 PSI of ground pressure and a massive bite thanks to the steel grousers.
Running 22" tires instead of stock 25" for added clearance under the body.
Reaching 15 MPH on hard packed snow relatively smoothly, despite the grousers.
Pretty unstoppable too.
