Nothing in the gas world will do any better.
I absolutely love my Tundra, but I don't live in Colorado, either.
A 3/4 ton diesel is probably the only real viable solution.
A 3/4 ton is a solution to too much cargo, if that is the problem. We don't know that it is.

A turbocharger is a solution to reduced power at altitude. There are gasoline engines with turbochargers readily available, eg the Ecoboost.

Driving within the capabilities of the vehicle, and accepting some reduction in speed when climbing steep hills, is the cheapest solution.

The half ton trucks will tow OK but they do strain. Manufacturers are trying for better fuel economy and sacrificing raw power in the 1/2 ton. They get over the pass, but need to revved to over 4,000 rpm which is a little scary.
The solution in a 3/4 ton with a bigger gas engine or the diesel.
I had the GMC 5.7L gas 1/2 ton and towed a 28' Flying Cloud. I traded the truck in December for a 6.0l GMC Duramax Diesel. What a difference. Just did a trip from FL to Oregon and into
the CO passes. The Duramax is just super. Fuel economy much better with diesel than the gas at 65mph and over. Step hills are climbed in some cases without a downshift.
I pulled AS at higher speeds than the gas and the range between fill ups is over 150 miles.
Diesel is the ultimate answer to your question, but you will pay $10,000 more. But you will keep the diesel 15 years and be totally pleased every day.

I enjoy towing my 30' with a half ton, but I live in flat terrain.
My Tundra handles all mountain ranges east of the Mississippi no problem, but we have no mile high grades like Colorado.
I would even still use my 1/2 ton for occasional trips to Colorado.
Not sure what I would do if I lived there...

I know you guys love your diesels and fully loaded megatrucks. Even though I have posted that our Tundra cruises over Colorado passes without any problems, it seems some don't believe it. But if you really want a megatruck and want to spend many thousands more plus more maintenance, go ahead and buy one. The diesel engine may last longer than the rest of the truck though a Toyota engine seems to go forever too.

You may see a Tundra pass you on the passes. Before anyone buys the Toyota supercharger (it will cut the 0-60 time from about 6.5 sec. to less than 4), the parts used to cost $4,000 and the dealer will surely charge a lot more to install it.

Bob, you'll notice that trucks cause a lot of emotion. Everyone believes they have the best truck. Someone actually does and it may be us.

Hi all. We just traded our 2014 23'D International Serenity for a 2016 16' Sport. Smaller is better we think......for state campgrounds here in the Catskill Mts of the Mid Hudson Valley, NY. We towed the 23D with a 2011 Ford 250, 6.7TD (purchased new in 2012). We really enjoyed the towing ability of the 3/4 ton Ford and always appreciated the "overkill." For us it's about stress free towing. Now, we require much less from a TV and will sell/trade the Ford for a smaller vehicle. The truck has 32,000 miles and just now feels broken in (though I'm not qualified to say this factually.) Anyone interested in a used Ford 250/6.7L TD for an average market price minus 10% just let me know. It's in excellent shape btw.

In any case, I always recommend towing with a vehicle heavier than the trailer by 10-15% and agree that 400hp and 425foot lbs of torque needed for towing A 25' AS in the "mountains." Recommend I emphasize. Different folks may recommend otherwise.

Cheers to all.

There are a lot of people who keep saying that diesels cost thousands more to maintain. But the new diesels dont cost much more than the gas engines to maintain. Yes you've got to fill the def tank with your oil change but thats only around $20.

A lot of people trying to sell their favorite truck to an op who has yet to describe his problem. Let's get the details first.

i use a 2013 Grand Cherokee Hemi with the factory tow package to tow our Safari 25 FB. Unless I'm heading south to Albuquerque, I have Wolf Creek to the east, Hesperus to the west and Lizard Head or Red Mountain to the north. The GC handles all of these passes just fine. There are a lot of late model Jeep GC on the market at reasonable prices that will get the job done if properly equipped.

I am glad you said that SpletKay. I was wondering too. I have an 05 model Dodge Ram and that Cummins engine is easy on diesel fuel.
It likes three gallons of Rotella synthetic, @ $21 a gallon, or regular Rotella $11.50 gallon in the summer. A new oil filter, (Baldwin, Fleetguard or Mobil 1) and new Baldwin fuel filter.
It gets a new Hastings air filter about every year, whether it needs it or not.
Its as easy as my Jeep to work on ( sometimes easier, more room).
I may have to change that batteries in it sometime, heck they are original.It has a drain plug on just about everything, transmission has a drain plug, transfer case has a drain plug, rear differential has a drain plug. All that is simple. I don't even have to buy that 'def' fluid or whatever it is.
It pulls that heavy-( beep) 28' Serenity with ease, from Virginia to PEI, then to Pascagoula Mississippi , and back to Virginia.

Yeah, I wouldn't take a plugged-nickel for it

The truck costs more to begin with, meaning higher insurance and registration.
The fuel costs more.
The oil changes cost more- it holds more quarts.
You change the fuel filter more often.
DEF.
When a turbo quits...
Toyota doesn't make a 3/4 ton diesel...

Bobgall,
Please don't take this as an insult but have you towed much before your purchasing the travel trailer?
Could this just be a learning curve on what to expect when you put several thousand pounds behind your vehicle? It is definitely a different experience than driving a solo vehicle. You should have more than enough vehicle to get the job done.

The 5.9 gas engine in my old pickup had about 180 to 200 hp tops. It was from the 1980's and laden with old fashioned smog equipment..... It would do the job pulling a 29' AS but you just went a lot slower and the driver was a bit more involved in how a steep hill would be tackled.

I have frequently traveled down in the Branson Mo. area in in some cases the grades on the roads down there exceed the standards used on Interstate Highways. With that in mind I configured my van with the largest gas engine that was available at the time (6.0 liter) and the best towing axle which was 4.10. Going with this combo also came with the HD GM tranny.

But as others have stated, your original comment about struggling is somewhat unclear. In many cases your success in climbing hills is based on wise use of gears and speed. In my case even though my vehicle is rated to tow in OD, when a large hill is looming, I will go ahead and drop out of OD at the base of the hill. This gets the RPM's up on the engine and I can hold speed going up the hill much better than allowing the tranny to make that decision later on in the climb. Secondly I've come to understand that trying to maintain the speed limit all the way up the steep grade is both a waste of fuel and for all intents impossible to maintain. I've dropped as low as 35-40 mph as I've crested some of these long and steepest pulls, but I don't consider that out of line considering the grade, my weight of my Classic slide out and with the knowledge that I still have two gears left if I need more pulling power. I've watched my diesel equipped fellow travelers and with equivalent sized trailers on the same hills, and with equal approach speed at the bottom of the hill, they end up maybe at best doing 10 mph better than me as we approach the crest of the hill.

Seems as if many individuals have different ideas on what works for them. Thats fine. But I have a 25 ft. with the 2012 Tundra 5.7, live in Colorado, and I love the truck. Going up to the tunnel at the Continental Divide (11,000 ft) with a full water tank I go 55 - 60 at 4,000 rpm. 2 people and a dog in the cab, maybe 300 lbs of gear in the bed. If I dump the water, which I may do after reading this thread, I'd be even faster.

This truck has a ton of torque for a gas engine, costs alot less than a big diesel, and the big plus is I don't have to listen to it. Diesels annoy me and my truck is a daily driver as well.

But if you want more and can afford it, go for it. I'm more worried about the brakes going down, than speed going up. I need to use the trailer brake manually sometimes on the steeper grades.

As said before, you now have 381 hp and 401 ft lb torque. Your truck is rated to pull 10,500 lbs. There is a factory supercharger made for that engine that would give you a whopping 504 hp, and 550 ft lb torque. Unbelievable!! That ought to flatten any hill in Colorado, and shame the Corvettes down at the racetrack when youíre not Airstreaming!

Iím new here, and Iím pulling a 34í Avion that weighs 9000 lbs fully loaded with the same 5.7L engine in a 2008 Sequoia. I go slow, and it seems Iím struggling through the steep grades of the Ozark byways. I was hoping the truck would have more pulling power, but you need to have realistic expectations of what any truck will do. However...

The last time we were on our way home from camping, I dropped my wife off to pick up her car. Alone in the truck with no backseat driver I approached the bottom of the next steep hill at my normal speed. As the truck nosed up, I leaned hard on the gas. The 6-speed transmission dropped down two gears, but without even breathing hard, it launched forward. I sailed over the top of the steep, albeit short, hill.

No need to drive your Tundra hard, but no point underestimating your truckís abilities either. The grass is greener on YOUR side of the fence. You have a great truck! Go enjoy it.

Actually Toyota discontinued the TRD supercharger. Boo!
I love my Tundra, but I love it even more because it is paid for- been paid for over 2 years- and has 53,000 miles- much towing ahead- Maybe I will buy a new Tundra when I retire, but I may have the last truck I will ever have.

There may be some of the superchargers floating around in stock, but they will not be produced/sold any more.
I'm sure there are aftermarket superchargers available.
I would love to do the supercharger, cold air intake, dual exhaust, and remap the computer to the tune of roughly $6,500.
How many 500 hp/500 ft. lbs. torque pickups are there?
$6,500 to hop up a paid for truck beats $65,000 for a new truck any day.

I thought about a factory supercharged FJ Cruiser for our 20' Airstream, then read a report of someone who had done it. Great power, but the fuel usage was scary, even towing on the level. Gas prices were considerably higher then, even more scary.
