Hi, first off you want fuel mileage and power to climb mountains at the same time. You will more than likely get one or the other, but not both. As for axle ratio 3:73 was the golden number for decades, but now with 6 speed transmissions and their very different gear ratios, taller than 3:73's can a do work. Next is the payload capacity of a half ton truck. It can be as low as 1,200 lbs to around 3,000 lbs. With, maybe, a 1,000 lb tongue weight, the first one [1,200 lbs] is almost useless.


As for the comment about 7,300 lb GVWR on a 25'er, this has been the rating on the Classics and most all of the 25'ers since the beginning of the front bedroom models. [my trailer is 6,300 lb rated] Also, [my opinion] 65 gallons of gas in a Buick is a death wish.

I would imagine a 60s era Buick could carry that much fuel...along with a few dead bodies in the trunk

(On the main topic, I tow with an SUV, not a pickup. I get about 11 MPG.)
The weight rating selected for each trailer, in part, is based on history.

When Airstream picks a given weight, several factors are taken into consideration.

Today, most owners pack the trailer to the limit and then some. Therefore the little extra weight carrying capacity assures a longer lasting life for the rubber rods within the axles.

If for an example the trailer will be lightly loaded, then simply drop the tire pressue down to 45 to 50 psi.

Make sure that the running gear is also properly balanced.

Andy

I have a thirsty V10 that gets anywhere from 7-10 towing depending on grade and headwind but I can climb any mountain. I replaced the 29 gallon stock fuel tank with a 47 gallon from Transfer Flow. Best investment I ever made as I can now travel up to 400 miles between fill ups and like Andy said, get out of California without having to fill up at high prices.

He doesn't say what year is his Ford V-10, but I have basically the same setup with the Transferflow replacement tank. I also have the Mike's 5 Star SCT programmer set at 89 octane/tow/performance mode. Pulling our 30' W/S, I average 8.5 towing at 70. Best truck I have ever owned including a bunch of diesels.


The only big problem I am hearing on the newer pickups is from my transmission friends; they all say that the new Dodge 8 speed automatic is prone to fail since it never stops shifting, especially when towing, and the internal clutches wear out sooner. The Ford/Chevy 6 speeds are almost as bad. The best tranny is still the Ford 5 speed TorqueShift and the older Allison.

That's a perfect TV IMHO.

Greetings Hoboplayer,

I have a 25' that I pull with a 2009 4.6L 3V HO 6 speed Ford F-150. It pulls great. Over the past two years I have averaged 12 mpg (calculated at the pump). I tend to pull it at limit 65mph or now, even 70 with the truck tires. I get a consistent 21 mpg on the highway not towing @65mph and guaranteed 20 mpg in most conditions @70mph. On my last trip I got 13.4 mpg but I was on back roads driving about 60mph through central FL. The 1/2 ton is optimum for the size as long as it meets your payload requirement. The ironic thing is that in 2009 Ford had a 5.4L as the next size up engine but it was only slightly more powerful and had I believe 30 ft lbs. more. When I was in northwestern SC near Table Rock there were some stretches where incline made the engine shift the transmission more often but it had no problem pulling at any time.

I will share that the most important figure is the payload capacity and having the tow package. I am looking to get a King Ranch Ecoboost in the next year I want a payload of around 1700 lbs. if possible. Just waiting for the aluminum F150! They are now saying that the new model will have greater towing/payload as an offset to the lighter truck.

Thanks to the great responses on this forum, I felt that I had the ammunition to make a logical decision. I chose to purchase a Dodge 1500, 2wd, 7.3L V8 HEMI, 3.92 rear end, Quad cab with 6.5" bed. It rides like a car and has some really nice features. One is a 8"display for the backup camera. Should come in real handy for hitching up.
Again, thanks everyone for the help...........Don

I would love to hear more about what others are towing and what they are towing with and the mpg they get. I think the data is valuable to anyone looking for a new tv.
