I grew up a with brothers, too, and so must ask:

Is this your older brother, perhaps even the same one whose stories about, say, his exploits with the ladies turned out to be whatchamightcall "a bit on the tall side"? ;)

No the ladies were never in the stories. He is a truck guy that spends his money on tweaking the truck and not on the ladies :B :h

That is what he is telling me and I have no reason to think he is exaggerating. Do not know if that is the computer or hand calculated.

2002 GMC 2500 HD 6L gas and I get around 11.7, 11.9 on a regular basis. I get a lot better in the mountains 12 - 14. Would love better but honestly have not found it.

My brother is getting in the 40's with his big diesel when pulling a huge cargo trailer. I would love to put my camper on his truck to see what happens. I suspect that MPG would drop like a brick but would be cool to see.

Let me try again....

I have a 2002 GMC 2500 HD with a 6L that gets around 11.7 up to 11.9 mpg as an average on most trips, flat to the foothills.

In the mountains I get a lot better from 12 to 14 mpg.

Would love a truck that gets better MPG but have not found one and I have looked at a lot.

My brother drives a 3500HD diesel tricked out with all the toys and can get in the low to mid 40's pulling their large cargo trailer on the highway. I would LOVE to put the TCer on his truck to see what it does to the MPG, have a feeling it would drop like a brick.

Hope that explains it better.

You are saying your brother is getting 40mpg with his 3500 diesel pickup truck while towing??? Is that average, or just what the onboard computer is reading for instant mileage while going down hill with the wind behind him????

With the camper @ 55mph according to the computer...20.5mpg
Without the camper in town according to the computer ....26 mpg
With the camper around town according to the computer ...12.4 mpg
Maybe I should mention we drive in Florida on flat ground . When we go to the mountains an we have the mpg does change. We have 185000 miles on the truck an the last time we weighted the combo weighted in at a little over 12200pounds
Happy traveling

That is really good highway mileage... but thinking about it, cruising at 55mph that certainly doable. And it would be interesting for you to hand calculate the mileage when you get a chance.

Truck/Camper in my sig getting 10.75 hand calculated highway mix loaded at about 12,800 lbs. I cruise at 65 on the freeway. It's worth noting that the computer consistently under-reports my mpg, reporting about .5 mpg low. Not a big difference though.

That's interesting... my 2008 F250 5.4 gas consistently OVER-reports mileage by .5mpg!

And I'm getting about what you are, towing a 21 foot TT. (This is a thread about Truck Campers, but I figured I'd add my mileage in just to confuse things...)

I bought a diesel pickup in 2011 to haul a camper. I would not do it again but instead buy a gas V-8 and get the 4.10 gears. The extra range with a tank of diesel fuel is completely negated with my having to drive further to find stations that pump diesel.

I pay more for diesel than I do for premium gas. I pay twice as much for oil changes and have to change the oil more often. And I paid an additional $9,000 to get the diesel engine and upgraded transmission. $9,000 would buy enough regular gasoline to drive my truck for more than 20,000 miles.

With my diesel and a 4,000 lb camper load the truck gets 12 MPG on average. With no wind and no elevation gains it can be as high as 13.5 MPG. With 15 MPH wind and driving the truck at 65 MPH the mileage is about 10 MPG.

If I was concerned about fuel economy I would have a 1/2 ton gas powered pickup with a 1000 lb. popup camper or get a Class B motorhome on the Sprinter chassis with the Mercedes 5 cylinder diesel engine and get 25 MPG or better.

I bought a Ford diesel new in 2007. Traded it in in 2010 for a Ford 6.2 gasser with a 4.1 rear. Dont regret it one bit, for much the same reasons above. There is no economy reason for a diesel, in fact it costs more to run per mile than a gasser. For pure power and torque the diesel wins out but its overkill for the purpose of carrying a 4k camper.
Milage @ 60mph with the diesel 12.5 mpg best case senerio. Milage with the 6.2 gasser a solid 10.5 mpg. Not enough differance to warrant a switch for purely mpg savings.

You have eaten more sour grapes about a diesel engine equipped pickup than anyone I have ever read. Go sell it and get that gas burner.

My minimum recommended oil change interval for my diesel engine equipped pickup is 7,500 miles and up to 15,000 miles. My truck is 8 months old and has over 14,000 miles.

You are also about the only person in the Northern hemisphere that I read about having a hard time finding diesel fuel.

The day I buy a gasser pickup is the day that they quit selling diesel pickups or I just don't have a real need for one.
