You keep skirting the issue. I'm not talking about towing. The Tundra is rated to tow something crazy like 10,000lb. I'm talking about weight that is *on* the truck, and the rating for this is somewhere in the 1,000-1,500lb range.You don't have to buy into it, you don't have to believe it, I don't really care. However, when someone asks a question like this it is ridiculous how the towing wizards go off on those of us who do understand the numbers and the liability and we are called the tow police. Some common sense would go a long way here.
Will a Tundra hauling 2,000lb in the bed (with beefed up suspension) be inferior in handling and stopping compared to one hauling a 10,000lb trailer? Or a big RV? Or big truck? Or a tractor trailer?
The answer in every case is an emphatic no. The Tundra hauling a load will be much better. Yet all these are common on the roads. It is *not* a safety issue! You can question whether or not the Tundra frame and axle are strong enough to haul the load, but that's a reliability issue. And the fact that so many are doing it without problems (while flying down rough dirt roads) should put your mind at ease.
