This Toyota Tundra, equipped with the specially designed air bag rear suspension, for towing, is incapable of towing anything on U.S. roads, particularly U.S, Interstates crossing our country... where a very large portion of these interstates are rutted, like a washboard, caused by over-weight trucks and the weather... and these rutted or rippled interstate roads last sometimes for hundreds of miles at a time... from western Ohio to Montana, easily 75% of the roads are in this condition. The truck is a complete hazard, and extremely dangerous to the driver and anyone else on the highway. It is dangerous to the highest degree and should not be allowed on any U.S. highway. The rear airbag suspension is controlled by a computer, this computer constantly levels the truck, and there is no way to over-ride this system/computer program.
