you will find a lot of opinions on here about towing a 5'ver with a Tundra. I tow a 35 ft'er ( non-5'ver )with a 09 Tundra.
The long of the short is that your gonna know its back there, being a half ton.
Can you do it, absolutely. You will be the only one to know what you are comfortable with.
I will say this My tundra has 80,000 miles on it, and I will be shopping for a 3/4 ton for my next truck.
