MPG 9.5, 2018 srw 3500 Limited

[Cam]

Hi guys, short story. Bought in Cali , I have 342 gr. 6 speed HD, 4x4 w/6.7HO
I've had it for a short time. This trk get between 9-10 mpg ..... period.... I hate it! Dealership has checked the flash. I'm About to delete it. Been sitting on it waiting on it to break 20k mi. Well I did. 23,860mi . Has anyone had this issue. Also dealership CANT figure out. No, ITPS, lane change warning on mirrors

Your pic shows towing. Are you speaking about towing mpg? Trailer specs and weight?

What is your idle time. I see average speed is 10 MPH, which is quite low.

 

[MtnRider]

10mph average is why your mpg sucks. You must be letting it idle a LOT.

Also, having trouble understanding parts of your post with the random punctuation and randomly truncated words... if you’re saying the TPMS and the lane change warnings in the mirrors don’t work, then my guess is they’re after market.

I’m guessing a Tire shop swapped the sensors and somebody put tow mirrors on it.

9.xx while towing a wind sale (5th wheel) is pretty normal--Dont believe the people that tell you they get 15 mpg while towing 14k lbs at 70 mph.

The alternative is a 1st or 2nd gen with 200hp and towing at 45-50 mph max. You will then enjoy 11mpg.

It seems like anytime I put a trailer of any kind behind my truck it defaults to 10mpg; 15k lb fifth wheel or 3k lb utility trailer, it's all about the same.

Noticed the same. Hooked up my 2000 lb cargo trailer.. same as my 7k travel trailer.

I hauled 1000 tons of hay and various pieces of machinery and did all local driving in my 5500 in my first year. Right now, I’m at an average of 14MPG. I am very happy with that. Not broken in yet.

Ok guys, sorry still getting used too responding. So the pic is for effect! To answer the question.
This is my mileage every day,! I HATE it. My trk is a Limited Edition! My tire functions system is not aftermarket, @54psi it is to be triggered to an in idiot light. Does not work nor has it from day 1, w/33 mi. on it.
I do have a lot of idle time. And it loves idle up with the reGen, def ect.
Here is a good question. Will the Exact truck born to live in California have exra emissions? Too answer, yes I purchased it up from dealership in SoCal.
I'm about too delete it, last ditch effort.
I miss my 2015
