RE: Failed Smog Test
If the HC is too high you are too lean. High CO is too rich. You may have an intake leak causing the lean condition. Check for bad vacuum hoses and anything that was disconnected. I presume the vehicle wasn't hooked up to a sniffer after the carb was put back. It should have been to at least validate the idle mixture.
High HydroCarbons is unburned fuel meaning too rich. CO means incomplete combustion, which could be form many reasons. Too lean shoots the NOx up.

RE: Failed Smog Test
Its definitely carb tuning. If its tuned right it will pass no problem. My old boss always used a cylinder balance analyzer for tuning. You can also use a wide-band O2 sensor. You could just try small changes on your own (lean it out), and just keep going back to DEQ for a free air-check (you don't have to do ay paperwork if you ask for the free air-check) until it passes.
The good thing about this all is you will stop wasting extra fuel once you get it tuned right. I just realized yesterday how big of a jump fuel prices made again:E

RE: How much HP & torque do I need ?
Performance is so subjective; some are happy to motor all day at 55mph & 35-40mph in big hills while others will clench their teeth is they slow from 75 to 74 on a climb. Most of us fall in the middle.
This is perhaps one of the best, most balanced comments on towing I have ever read here.
Ha ha. Not only that, but some guys want need to hold 75 and never downshift. OMG DOWNSHIFT MY TRUCK IS FALLING APART I NEED MORE POWER!!!

RE: what do you think
Get an E350 with the V10. You will be over rear axle and GCWR on a 3/4-ton van with that size trailer.

RE: Wandering Nightmare
Hi,
Wheelbase on E-450 is 176 inches, not 171.
55% would be 320 inches. You are above 50% so it is not length.
How fast are you driving?
The wheelbase may have been modified. Pretty rear for RV makers to use the stock wheelbases. A 171" wheelbase would have been extended from a 158" frame.

RE: Switched from Suburban to Van
For a front recovery point, you may want to look into a hitch receiver. It'll give you an anchor while also providing strength to the frame end won't get bent during a pull. And it'll allow for carrying bikes up front, and can be used to pushing a trailer into tight places.

RE: Sprinter Chassis RV
I suggest doing some more math first. You will likely take a BIG hit moving from your class A.
Will you be making payments on the new RV? Split the payments by the miles you drive each month, and add that to your fuel-cost per mile. I strongly suspect you'll find the more fuel efficient motorhome is not more cost efficient, especially since you already have one now. Even comparing 2 new coaches, the extra cost of the Sprinter will take a VERY long time to recoup.

RE: Good bye V10. What should be next?
Yes, get a f350 with the 6.2. They are not that much more money. I have 3.73 in my V10 and I am considering changing them to 4:30 or 4:56. So I would recommend a 4:30 for your new truck.
Congrats btw!
Remember the new 6-speed has a much lower 1st gear, and all the ratios are closer than the 4R100. Lower diff gearing isn't near as important with that new transmission.

RE: A question about transmissions
As hinted above.... It's really the motor not provide braking, and has little to do with the transmission. Even if you added a bypass switch to manually lock the TC, you still won't have any engine braking (My '03 work truck was an F650 5.9CTD/6-speed man). You really need the exhaust brake.

RE: Payload capacity for typical class C
Short answer: Somewhere between 1,000-4,000 pounds.
Can you be any more specific? Like model, year etc.?
That's kind of like asking "what kind of gas milage does a car get?"

I don't like exterior parts made from plastic. Especially critical parts.

RE: Most reliable connector. semi 7 pin or RV blade ?
The endurance plug does actually hold up WAYYYY better than most. I have a 7-way on the front of my van (for the dirt bike carrier) and a standard plug would get broken in weeks. I've had the Endurance plug on there for almost two years now, and it's still intact.

RE: 1986 Chevy G20 3/4 ton, 6.2 Diesel
While I think you'll make it... Keep in mind that even a short tow for your truck and tailer if you don't make it will cost many times more than what it costs to rent a U-haul for a day.

RE: Luxury Diesel SUV as tow vehicle
All of the SUVs you listed will are not rated for the tongue weight of a 6000 pound trailer (at 15% = 900 pounds). Jeep says they offer a Class IV receiver but they don't list the tongue weight rating that I can find.

RE: F550 Chassis Super C power ratings
Also Ford is quick to cancel your warranty on your diesel if you re-program it for more power. Pretty risky since it's $12-20,000 when the fuel pump goes out on the 6.7L. Plenty of information on both topics on the Ford diesel forums, and also good info on the fuel pump in the Tow Vehicles section.

RE: Need Advice on E450 Engine Mod
Tuning requires uploading a new program into the PCM using some sort of programmer. 5-Star tuning seems to be the best for the V10, but I'm also happy with my Predator after making some changes to the canned programs that came on it. But to get the best gains, you need to combine a new program with better breathing. With all those changes, the 2-valve V10 can out-perform a stock 3-valve.
Is it worth it? For me it was. I like being able to pass cars when going up the pass even with a trailer in tow. But if you are more patient than I am, or mostly stick to the truck lane anyways, then stock power levels should be fine.

RE: With the E-series going away, what for future Cs?
E-series cutaway has been committed through at least 2019 with the vans through at least 2015.
Express Chassis can't go past a 209" wheelbase because the frame is smaller. So sticking a longer body it makes for bad weight weight balance. You can pretty much see the 30' cutoff on the Express from all the big RV makers. Plus, GM has never even hinted at a long-term forecast for the Express. THey've cancelled truck lines before with only a couple months notice.
Ducato/Pormaster is FWD. Not way would you be able to pull a 30'+ coach up any sort of a grade without madly spinning the tires.
A while back I rear one article stating Ford will stick the Transit cab on the F53 chassis for a larger cab/chassis (i.e. T550). But I haven't seen anything lately so maybe that has been put on hold. Ford is maxed on F53 production anyways because RVs made a HUGE jump in sales this year (and there is no longer Workhorse to compete with).
Transit pretty much matches the Sprinter axle and GVWR capacities, so I think you'll see see it taking some of the Sprinter market, but nothing bigger. It's main advantage will probably towing capacity (assuming they maintain the F150 ratings), and lower cost.

RE: swap 5k lbs hitch to a 10k lbs hitch
Some DP chassis are actually limited by the rear engine sub-frame. I can't imagine it being a problem on a stright-frame DP (do they still make those?) but as mentioned, check with the manufacturer.

RE: synthetic trans fluid
What 74vette said. Most EO trans fluids are full synthetic now, including Mercon-V, Mercon SP, Dex-VI, Chrysler ATF+4.
They all switched for good reasons. If you have an older fluid like Dex-3 or Mercon (without a suffux) then you will probably get longer transmission life if you switch to one of the newer fluids.
