heres the thing about manufaturers tow limits, they mean practically nothing as far as safety is concerned. Safety is not the determining factor when a vehicle manufacturer puts a tow limit on their vehicle. Do some research, you will find that two identical trucks, the only difference being one is a stick shift, the other is an automatic. will have very different tow capacities. The same goes for two identical trucks with different engines. As far as safety goes, they might as well say Red trucks can tow twice as much as white ones.
Nissan. I was doing some research of Nissan Frontiers. This year they bumped there tow rating up to 6500 from 6100 but changed nothing on the truck. Why did they do it, because Toyota bumped theirs up. So last year it was only safe to tow 6100 but this year, same truck different model year, its safe with 6500????.
Another example, I'll use GM because you mentioned it. GM 1500 short beds have the same tow capacity as the identically equiped long bed trucks. We all know its safer to tow with a long wheelbase vehicle verses a short wheelbase vehicle but GM rates them the same. Why??? because safety is not factored in.
I dont mean to sound like I dont put importance on safety, Im just saying I dont depend on the truck manufacturer to tell me whats safe and whats not based on some arbitrary number they place on a vehicle. Whats safe is something I will determine for myself and the drivers around me will have to live or die with my decisions.
Anyway, it doesnt matter, thanks for your opinion.
