I have seen a so called rig calculator somewhere and now I can't find it. Anyone know the whereabouts on such a beast. If I remember, it took your wheelbase, approach angles, gearing, motor, and several other things and made some type of rig rating. I thought it would be fun to see how my jeep ranks against the neighbor kids electric barbie jeep. The barbie jeep wil probably kick my arse:darn:. I thought it used to be here on the site when they used to have the map and locations. But, I am getting old.
