"Enjoyment"
This is the main reason I went to a full sized truck with plenty of power. It really is nice not giving any thought to if I can make it up over a pass. Coming down the other side I still think about though.
I'm on my 4th tow vehicle, I've gone up progressively in size to get more "enjoyment" out of it.
My brother has an 08 Sequoia with the 5.7L and a 5000 lb bumper pull, hates the mpg (about 10 while towing) but loves the ride and power. You'll should do a bit better on the mpg then he does.

Chuck does that wind generator you have mounted on your truck cut down on mileage?

When we bought our Scamp, the sales office had pictures of various tiny vehicles towing Scamps. By putting the axle so close to the trailer's midpoint, you could get the tongue weight to about anything you wanted. I think there was one with a 13' and a VW Beetle. Sway city here I come......

(Of course I can also remember really safe things I did, like towing friends disabled vehicles down the highway with a chain.....)

Was hoping to see an engineer weigh in on this but I've done some research and am sure to be corrected if there's any errors: Toyota doesn't mention anything in their Tundra specs about engine grade braking. They do mention large brakes. On the other hand several including myself have reported the benefits of the grade braking on their GM trucks/suv's.

From GM: Available on Savana, Sierra, Yukon, and Acadia, tow/haul mode raises transmission up-shift and down-shift points to alternately give you more power to accelerate, and greater access to engine compression for deceleration with less noise and harshness. Excess shifting when towing or hauling excessive loads is also reduced.

Do Toyota trucks have this same technology?

If you have the 5.7L V8 the answer is yes. There's a button for 'tow/haul mode' that holds the lower gears longer to assist in acceleration, deceleration and stopping.

But is that the same as engine grade braking with "greater access to engine compression for deceleration", and if not is there a significant difference by not having it or are you relying on the service brakes more?

Yes, it includes engine braking, at least according to Toyota's FAQ:

When should I use Tow/Haul mode in my 2014 Tundra and how do I operate it?

Hi Brent & Cheryl

We are waiting for an Escape 21 to be built for us by mid-May 2015 and looking forward to an easier tow with our 2005 Tundra (285 hp). Until this summer we were towing a 19' Nash trailer that is at least 800 lbs heavier than the Escape 21. We live in Surrey, BC and frequently drive the Coquihalla Highway to the BC Interior lakes to flyfish. The only really slow point on the Coquihalla summits was by the snow sheds where the best I could do was 70 kph (45 mph), but the rest of the time I would be doing at least 90 kph (55 mph) and usually the speed limit. This is with the truck maxed out in carrying weight and combined vehicle tow weight. If we didn't have the boat on top and the motors (outboard & electric) and tons of extra fishing/camping equipment the tow would be much easier. When we took our trailer to Utah in 2012 without all the fishing equipment we found that the towing was much easier than the Coquihalla. But even then our little 4.7 L V8 on the Tundra had to work pretty hard to maintain the speed limit. If you get the larger V8 on the newer Tundras it should be an even better tow. The reasons we haven't upgraded to a newer Tundra are 1) don't have space in our garage for the larger truck 2) harder to park around town 3)expense. I'm expecting our truck to last for many more years based on the experience of other Tundra users. I've attached a photo of our fully loaded unit ready for a trip up the Coquihalla.

Here is my experience with this, so far: After our Escape rally in Moab last May, I spent a few days in Canyonlands NP then decided to go to Dinosaur National Monument, north of there near the WY / CO / UT border. I was pulling my Escape 21 with a Toyota Tacoma V6. I made the mistake of letting the Garmin pick the route. It took me into Colorado then north on state road 139, over an 8000' pass! Boy was I ticked off. I had to slow down to 20 mph in places. The good thing was the speed limit was often around 20-25 mph anyway on the high-altitude switchbacks, and there was no traffic. In the future I'll be more careful.
