Well I am getting up early in the morning to go get my trailer. We just bought a 2002 Carriage 35' cameo triple slide. Its going to be home for the next couple of years. Cant wait to see how the truck pulls it. The 04.5 will be about maxed for wieght as the trailer is just under 10k. Its 6 hours down so I should be able to post some numbers on the loaded MPG. I cant wait as I love to pull trailers.

 

With a GCVW of 23k I'm not sure I follow you why the weight will be about maxed.

Sounds like a fun trip and a nice trailer though.

 

My '03 SO pulls 10,000 lbs. at high altitude without any trouble. Don't worry about a lack of power.

(Oh I forgot, being an 04.5 you have a catalytic converter... )

 

Trucks gross is actually only 21K as it has 3.73s. Truck is near 8K and the trailer is 9,865lb empty. Pin wieght between 1700 and 2100 lbs depending on what literature you go by. My truck is a 3500 SRW so she will be around max GVW of 9900lbs. Not to mention there will be a few things in the trailer that come with it. A duellie would be nice but wouldnt fit at the house back when I bought it. Sometimes you just have to make due with what ya got I hope you are right about the power. There are some nice grades coming up I-20 heading into SC. Empty the boost will climb up to 18 PSI.

 

My 5th wheel loaded weighs right about in that range, and our pickups are similar. I'm under all ratings, but if I carried a bunch of gas jugs or anything else heavy in the pickup it would easily put me over GVWR.

I have plenty of power for hills, and get just under 12 mpg at high speed interstate, but as high as 14 on slower 2 lane highways that are fairly level.

 

Well I got the trailer home last night. 700 miles in one day with 350 loaded. The truck avg 10.6 MPG on the way back. I would like better but considering the grades up I-20 from Atlanta to Columbia I cant complain. I ran 65-70 MPH to keep her in the sweet spot. Everything pulled well and handled nicely.
I am disappointed in the motor. I had to run without the box to keep temps down. I had to really work to keep the EGTs at 1200 or less even with the stock programming. Anything over 2100 RPM skyrocketed the EGTs. Boost was 20 -30 PSI at these times so it wasnt air flow. Engine temps never exceeded 210 degrees. Accelerating from a stop took forever. The lower gears would shove the EGTs so fast that short shifting was the only way to get the load moving. Something seems off about this! I think a turtle probably out ran us a few times. Literally took 1.5 miles to hit 65 MPH! Yes the air cleaner is clean. I will need to do some investigating before I haul the trailer again. I really wish I had put the hitch in the old 12 valve right now.

 

I'd say something's wrong, here's my $.02 worth:

In my experience, if I can keep the boost at 32-33psi at neawr WOT, my EGTs stay right at or under the magic 1300°F. Of course I don't keep it there all day. I'd shoot for a little more boost if I were you. You may be pleasantly surprised.

And if you have gauges, why "take the box off"?

 

I would think something would be wrong to.

I just pulled to WV and back and on the way back in the hills on I77 I was able to keep speed all the time 65-70 mph and was running 23-24psi.
My truck is all stock as far as power and motor.
I grossed 20K on the way back 10K truck/10k trailer got around 17mpg round trip was around 550+ miles.

You should be getting a lot better then that should you not??

Yeah, I think something is odd there, too. My truck is stock, and I can hold it to the floor up an 8% grade forever and not get close to 1200, and if I use a lower gear the EGT's drop.

I'd expect your 600 to run a bit hotter EGT's, but not by that much?

Could you have a boost leak, or maybe barked & tweaked the turbo?

 

18 PSI is empty cruising up the interstate on a slight grade. More can be had if I hammer the throttle. Sorry for the confusion. I pulled up to 30 or 32 PSI on a grade loaded and ran around 18-22 PSI most of the time. There is more boost to be had as the truck will spool up to 40 PSI but I couldnt give enough throttle to spool that high before the EGTs rose while pulling. I cant even go 2/3 of the way through 2nd gear before breaking 1300 degrees at near full throttle! Forget it with the higher gears. I had to turn the box off as it was running the EGTs up faster than stock programing.
I did find out that the trailer is heavier than It is supposed to be. She is almost 12k empty. That brings the Gross near 20K. I talked to Cummins (old timer that worked R&D for 31 years), a local Cummins garage service supervisor, and Quad today. They all seem to think something is off also. They thought either the thermocouple (less than a year old) is off or I have a bad injector. The oil has always been clean so I think the injectors are fine. ie no fuel in the oil. also idles perfect with no white smoke. Interestingly the truck hit 18.3 MPG the last tank back and forth to work before the trip and 17 MPG empty running 75 MPH all the way down for 350 miles. These numbers are spot on for interstate and a slight improvement around town.
I guess the only thing to do is pull the box and take it to Crysler and see what STAR has to say. Something is amiss here. Anyone have any ideas?

 

Under 10K for a 35' triple slide? That sounds pretty light. If you get a chance, weight it before you start loading it. The actual weight might surprise you.

 

The title says just under 10K but the Sticker inside is the trailer is just under 12K leaving around 1800lbs for my junk. I will wiegh it in a couple of weeks before I move to VA. The dodge has an appointment on Monday so hopefully they figure out what is wrong with the motors EGTs and replace the steering wheel. The service manager asked what the whoshing sound was as I had the exhaust break on. Got a kick out of that.

 

Well the truck went to the dealer and they couldnt find anything wrong with it. Go figure. I had them do the MPG flash in hopes that there is a difference in the program. The service writer seems interested and is going to try to talk to the DC engineers, I am guessing star, but I am not holding my breath. I need to tow a lighter trailer to VA this weekend so hopefully I can see an improvement with that. End of my update. If anyone has any ideas let me know. Thanks.

 

i can hit 1200 empty just spirited-ly rowing the gears. i have yet to tow heavy in hills since i got my gauges tho. where do yall have ur pyro probe mounted at?

 

Pre turbo. Problem was keeping the EGTs at a low of 1200 degrees. Not hitting 1200 on accelerating. I usually see 950-1100 degrees doing 0-60 MPH empty. I think the turbo exhaust housing is killing it.
