The running boards came from Ford. The lights on the running boards were done by Profab in Manheim Pennsylavania. I am weighing just about 19,000 lbs on the trailer loaded with gear and the two harley's. We have a transfer flow 50 gallon under the cover tanks with a pull rite 25K super 5 hitch. The pin weight is about 3200 lbs. I scaled everything at 29,020 on a recent trip. I don't get much squat. We do have the 5th airborne pin box. The best mpg trailering was about 8.6 but the 7.6 seems to be the number in the mountains. The truck ran great but now is being repaired after bad fuel. They had to pull off the cab and replace the injectors and high pressure pump. The truck stop is paying the costs. Now, I just hope it runs like it did before the accident.

I picked up my `08 F-450 almost 2 weeks ago. Drove the heck out of it to get to 1,000 miles before my first pull. This truck is awesome. If you are looking for a Super Duty to pull a 5er, go with the F-450.

First, This truck drives more like a car than a truck. Much smoother ride than my `06 F-350. The steering is incredible. Very tight turning radius. My trailer weighs 16,250 and there is almost no squat at all. Taking off from a dead stop is smooth and powerful. With the brake controller set at 9.5, the stopping is awesome.

O know I sound like a walking TV commercial, but this truck is incredibly awesome.

By all means, get the 450. It is much more truck for not a whole lot more money.

We just towed with ours for the first time this week, a 150 mile trip to the coast over a mountian pass and lots of curvey roads. What a difference from our 2000 350 SRW truck. Like you, I took awhile to decide between the 350 with 4:30 rear or 450 with 4:30. Look under the back of the 450 and compare the size of the rear axle to the 350. Brakes are larger all around.

If you are pulling only 15 - 16K pounds, you can drive any one of the three major trucks in the one ton dually version - - take your pick. I would definitely opt for the 4.10 rear end in any one of them as a balance between mileage and good towing performance. The Dodge will probably give you the best overall mpg. Other than that, look for overall reliability and frequency of repair records you can find on major internet sites all over the web for each of the three trucks. Any one of their 1 tonners will handle that rig just fine - - no need to go any larger. Just look for reliability and which one fits you and your pocketbook the best.

If this pricing is still correct, you can buy a Ford F450 for under $40K. That's less than for a F350.

We have had our 08 F350 for 2 months now and MPG is 14+ unloaded. I find that nursing this beautiful vehicle, keep speed 55 or under when possible and RPM 2K or less will break it in right. Also get it to shift into OD right around 40 MPH and accelerate from there. This 6.4L engine has more than enough power to not have to tromp on it. I'm looking for 16+ MPG unloaded by the time we get our fiver next spring. As far as towing, with TowBoss, your Combined Gross Vehicle Weight (CGVW) is 17.7K lbs, depending if you have a dually and 4X4, etc. The TowBoss setup requires a 4.30 rear and so your fuel usage will be greater than if you have a SRW with 4.10 rear. By comparison, an F450 with the 4.30 rear, your CGVW is only 2.3K higher at 20K lbs. You also have a significantly higher price tag.
You need to visit a Ford dealer and get a copy of the 2008 Super duty RV & Trailer Towing Guide. You can also check various web sites for this info.

Don't ignore the GVWR penalty of a SRW truck - this is (as I noted in an earlier post) the "gotcha" when looking only at GCWR and "manufacturer's trailer tow ratings" when a heavy 5th wheel with its ~20% pin weight is involved. You may be fine on GCWR and within the "manufacturer's trailer tow ratings" but well over the truck's GVWR. Buy the right tool for the job the first time.

I responded in your other post too.

I towed a heavier trailer (16,500 GVWR, 2700 pin wieght) with the F-350 it it towed very nicely. My F-350 had the TowBoss package as well. And I was NOT over the limits of the truck. If you are certain you will not end up with a much heavier trailer the F-350 will do fine. Based on the weights you list on the other post, you may be at the very limit (if not slightly over) with 4:10's. Depends on the actual weight (usually different than what you read) of the 5er. Will the 4:10's work for you? I'm sure they will. I doubt you would see very little degredation in performnce on a hill vs. 4:30's. What I've read, you will get about 1 MPG better with the 4:10's.

Sorry if I appear to be too anal, but we hear too often around here is that someone buys their truck and then it turns out to be not enough when they find the trailer they love. You are doing it the right way buy deciding on the trailer first, then get the truck you need.

Guys, for the couple extra thousand it may cost, upgrade to the 450. I had a f350, it towed my 35' "OK" but I do beleive I should have had a heavier truck. The newer trailers have a higher weight.
I will also say that MOST not all people will upgrade at least once if they really enjoy RV'ing. With a F450 you have allot more options down the road.

( I always had the wrong truck, and lost money going though the process, as did others. That is why this site is great so you don't make the same mistake I did.)

The "gotcha" clause in the brochures that cite the manufacturer's trailer tow ratings is buried in the fine print with a statement similar to "None of the truck's other ratings are to be exceeded when towing."

Wow, how nice to find an RV site where the moderator understands how pin weight is payload and keeping within your GVWR is important. I have recently been banished from a popular owner site where the moderators know very little about truck specs. Popular high posters that run over 1000 pounds in excess of their truck GVWR ratings are constantly telling newbies that you do not need a dually to haul the heavy fivers because their own overloaded SRW trucks have never let them down. Disagree with this core group as some of them like to call themselves and you are kicked off the site.Some newbies go out and buy SRW 3/4 tons to haul 14000 pound Fifth wheels and thank these guys for their opinions. Unbelievable!!
This is a site where facts are more important than personalities and that is the way it should be.

Thank you for the kind words. I know some of the sites have a lot of "experts" that are driven by compassion rather than facts and the response reflect this compassion.

Rusty and I are both engineers and deal with specifications and numbers on a daily basis. You have to have a basis for your findings that need to be backed up with experience and ratings.

Oh, and WrenchTravler, glad to have you join our site.

It's just as refreshing to have a member who understands the importance of "doing it right".

The final important item to remember is that it's ultimately YOUR responsibility to be sure your tow vehicle is properly matched to your rv. If you get into an accident with an overloaded tow, none of those "experts" (including the salesperson at the truck dealership) that told you the 3/4 ton SRW truck will easily haul that 40 ft loaded 5-r will save you from the lawyers spearheading the lawsuit.

Take your time, listen to the experience on THIS site, do your homework, run the numbers, then run them again. You won't be sorry. You will then have a combo you will enjoy & be secure in the knowledge it's safe out there on the roads.
