I found this...
Mauri Big Bear: For those of you that don't remember Mauri products, they were inexpensive kits that came out in the late eighties, and they were pretty much gone within a year and a half. The Big Bear was their monster truck, with tires that measured four inches across! It sported full spring suspension, and the smallest ball joints in the steering linkages. All it took was one good hit, and the steering linkage would pop right off. This thing sucked! But it was impressive to run.
