Towing G. D. 2670MK Question

Grand Design 2670MK Is anyone towing this TT with 1/2 ton truck or maybe Tundra TRD 4x4 5.8L?????
I'm thinking if i purchase this G D 2670MK I'll need to have a 3/4 ton truck.

All comments appreciated

IMO, 3/4 ton for sure.

With my Tundra I towed a 30' (2' shorter than yours) 7000# on the road (1500# lighter than yours), and it was a handful at times in windy conditions or when a semi passed. I pulled the same TT with a 3500, and hardly knew it was there in any conditions I drove in. Power was never an issue even in the mountains, but it was at times evident that I didn't have enough truck.

Any 3/4 ton will handle it easily and your stress level will be reduced significantly.

Agree with needing a HD truck.

Anything over 26í, and 7k lbs I would go larger than a 1/2 ton.

We tow a 23í and 6k lbs trailer with our 1/2 ton, and itís a great combo in all conditions.

Where and how are you going to use that trailer? If you are camping at local State parks and only tow on back roads with the top speed of 50 mph your Tundra will do that. At slower speeds you can tow more.

I maxed out my truck for 3 years camping local. It was fine up to that 50 mph speed. I had a short 2 mile run on the highway. Just one exit. It could do that also because I got on the ramp, stayed in the right lane and got off on the next exit 2 miles away. I could tell this combo would not be good on a long trip. At 60 mph what happens is my truck would get squirrely and I needed to use two hands to stay in my lane. That was doable for 2 miles. I was towing a 26.5' travel trailer with a truck with a wheelbase of 122". That exceeded the wheelbase to trailer length guideline.

After 3 years I traded for a truck with a 147" wheelbase. That truck was night and day better. This truck could tow the same trailer, loaded the same way with the exact same set-up at 72 mph and was rock solid. Not even any affect from semi trucks as I passed them or on rare occasion they passed me.

So, if camping local where your top speed will be 45 - 50 mph on back roads you will be good. If towing on the highway at 70 mph with semi trucks you will need a 3/4 ton truck to control that trailer.

Oh, I looked up your wheelbase on the Tundra and it was good for about a 28' trailer.
