Hey Guys!

We'll be picking up a 2007 Tundra Crew Cab 4WD this weekend. It has the 4.7 in it. Not really looking to make it our primary tow vehicle but wondering if anybody does tow w/ the 4.7 Tundra. Travel Trailer weighs approx 6000lbs ready to camp. Also, aside from the engine is the drive train the same as the 5.7?...I seem to remember the 5.7 being a 6 speed tranny and the 4.7 being a 5 speed? Rear ends the same?

Looking for honest opinions and real world experiences......

Thanks!!

TCOM -

We have the Toyota listed in my signature. It also had the 4.7 (however) the newer 4.7 produces more HP. We have towed our T.T with it on 11 trips so far with no problems at all. Granted it has all been on the flat lands of Florida / GA. Our T.T weighs in at approx. 6200 / 6300 lbs.

Good luck / Happy camping.

The drive train for the 2011 Tundras is different for the two engines. The 4.6L has a 4:10 with the tow package and the 5.7L has a 4:30. I thought my 4.6L was close to max with 5000lb wagging behind. I'm pulling 8000lb now with a 5.7L with ease. Two completely different animals. That being said, you'll need to watch the payload capacity of the truck. That's the weak link on every 1/2 ton truck. Mine is fine for me because it's only me and DW and all gear, food, and clothing goes in the trailer.

The last year for the 4.7 iron block was 2008.
It was replaced by the 4.6 aluminum block. the 4.6 has 310Hp, the older 4.7 has 276HP.
The 4.7 has a 5 speed and 4.6 a 6 speed. Both have the 9.5" 4:10 rear diff.
The 5.7 has a 4:30 10.5" rear diff.
The 4.6 is a more powerful engine and is lighter than the 4.7, plus the extra gear on the 4.6 is plus.

So in your opinions....could an 07 w/ the 4.7 drivetrain in it handle a 5500 lb 30' travel trailer? At least better than my 07 Suburban.

If the weight of the loaded trailer is less than the towing capacity of the truck, and the hitch weight combined with gear and passengers does not exceed payload capacity, it will handle it. IMO you'll be at the high end of the towing spectrum for that truck, but with a properly setup WD and anti-sway, you'll be fine.

I had the 4.7 in a 1st Generation Tundra and it worked very hard towing 5000lb.
My 2nd generation 07 Tundra tows 5k very easily. If it is not late, look for a Tundra with the 5.7.

Agree on the 5.7L. Using it for a daily drivem the difference in gas mikeage is insignificant and if you are going to be doing a fair amount of towing, you'll be much happier with the 5.7L. It also opens the way to upgrade to a larger trailer, if you desire. No one ever woke up one morning and said, "Man, I wish I had less truck".

Also, considering the age, tow capacity, and payload of the Burb, you may find it to be less suitable as a TV than you thought.

I do admit I'm partial. I love my 5.7L and the 47 gallon fuel tank.

Just to compound on this... I think the 5.7 has better gas mileage than the 4.7 anyways. I would encourage you to test drive a 5.7 before you commit to a purchase. You will be at the high end of your towing capabilities with the 4.7. Being at the high end will cause greater wear and tear and much lower gas mileage.
