MPG?? What is the real difference. 3500 4x4 quad. Who owned the gas, then went diesel. Reason I ask, saw two identical 3500 4x4 quads at the dealer today. Diesel payload was 4180, v8 was 4900. Im the one started the 4000lb camper thread.
 
I don't have a real qualified answer as my previous truck was a 1/2 ton 360 auto with a 3. 92 rear axle ratio. I now have a 1 ton with the great Cummins with a 4. 10 ratio and a two wheel drive as was the last truck was a two wheel drive, so your question and this reply may not be what you want. I pull the same enclosed car hauler so that has not changed. The mileage when I pulled with the gas engine was around 8-9 miles per gallon if I wanted to drive 70 miles an hour. With the 1 ton diesel I have gotten 12-13 miles per gallon. Just my quarter's worth. Oh, by the way I have heard the V-10's do not get any better mileage than the 360 just has more get up and go power.

Well the payload is different due to the extra weight of the cummins. Just like the 2WD can carry more than the 4WD.

I have not owned a gas V8 or V10 dodge so I cannot offer any real numbers.

But, you will get much more bang per gallon in the diesel than the gas, the V8 will have to work harder, therefore use more fuel, and dodge is not known for economy on it's V8's (Or V6's for that matter, a good friend has a V6 2wd durango, lucky to get 16 or 17 on the highway, our 350 V8 Suburban gets over 22 on the highway).

The V10, well much better for the wieght than the V8, won't have to work was hard, but still won't be as good as the cummins per gal. Or longevity either.

The cummins, won't have to work at all #ad
, plus it sounds cooler. Hehehe

Another factor is the price difference in the gas eng vs. the cummins. It's about 6 grand, and you will have to drive quite a bit to realize the savings in fuel.

But if the cost of the truck gas vs. diesel doesn't matter, I'd go with the diesel.

I did #ad
And I have nothing to haul or tow. The more I drive itm the more I love it. I'd buy another one. Just wish Dodge made a crew cab like the super duty.

Maybe I can help. I have owned one of each. The mpg figures below are for an unloaded truck, since I don't tow enough to have accurate input.

My first truck was a 98' 2500 QC SB 4WD 5spd 360. With mostly city driving I would get between 13-14mpg. Interstate was about 15mpg. Mileage wasn't great, but it wasn't bad enough at the time to bother me much.

My second truck was a 99' 2500 QC LB 4WD 5spd V-10. With mostly city driving I got 10mpg. Interstate traveling I got maybe 11mpg. I loved this truck, but I was constantly filling it up. The best I seemed to get out of it was 11mpg. To make it worse, it would ping with 87 octane gas, so I had to use a minimum of 89 octane.

My third truck is a 99' 2500 QC LB 4WD 5spd Cummins. I think I get great mileage with this truck. Around town I get 17-17. 5mpg. On the interstate I get 20-21mpg. For what it is worth, I have towed a couple of times with about 5-6K pounds. Around town it got about 16mpg. I wish I had bought this truck to start with. One note, don't expect great mileage to start, mine steady increased for the first few thousand miles. And at 16K miles, I don't think it is fully broken in yet.

In short, I would get the diesel. When you look at it on paper, the gassers seem to make since. That was my logic with the V-10. However, after owning one of each, the Cummins really makes the truck. I would have saved some money if I had bought it in the first place. I drove everybody around me crazy talking about diesels until I got one. Now this truck is like a member of the family.

As for the camper, I don't know much about them. However, I haul(constuction supplies, lumber, etc. ) with the truck bed all the time. Based on that, I still feel the diesel would work best. If worst comes to worst, get the truck and get a smaller camper. It is worth it.

I owned a V10 #ad
same configuration as my diesel: 4x4 club cab, 5 speed, 3. 54 gears. V10 got 10-11 in town, 13-15 highway, towing 8-10. Diesel gets 18-20 in town, 19-21 highway, 13-15 towing. Diesel has a lot more power and torque, less need to downshift whereas the 'ten had to be downshifted to 4th on the hills towing all the time to get it over 2000 rpm. Oh, I put 255-85 tire on the diesel while the 'ten had stockers; I didn't really gain any mpg with the tires.
THERE IS NO WAY I WOULD GO BACK TO A GAS PIG AFTER MY CUMMINS!!!
With some judicious and cheap uprating, the Cummins makes over double the hp the 'ten could make dollar for dollar in upgrades. The option pays for itself easily between fuel costs and resale.
"Just do it. "
 
I've towed with several big block(454) Chevys. There's no way I would go back go a gasoline engine!!! The big blocks pull good at low altitude, but get them to the high country and they are wimps. I can't afford to feed then either. Wait until they get a little carbon build up in the combustion chambers and then you will really spend money burning higher octane fuel to keep them from "pinging"!!

It's turbo charged oil burners for me!!!

Same here, I have a friend that has a 454 and he pulls his 24' cattle traler and gets 6mpg's at best. I pull a 20' cattle trailer and a 30' flatbed that I haul hay on and I have yet to get under 10mpg's towing, and that is running it hard in the hammer lane. I guess I like to see peoples faces when they see a 13,000 lb load go by them on a hill. #ad
oh yeah my frind with the 454 has never broke 10mpg empty.

I spent well over a year trying to decide between a QC 1500 4x4 5. 2 5spd and a QC 2500 4x4 5. 9 5spd. I never considered the V10 because of mileage and the Cummins because of the option price.

I chose the 1500 because hp/weight and tq/weight were in the 1500's favor. Mileage was never over 13. 5 and 12. 5 was the norm; the truck was fine on the flats and gutless in the hills.

I finally did a 10yr cost analysis of oil, filters, fuel and monthly note (same interest and term) and the 1500 was going to cost more in the long run. I decided to lose on trade after 6 months and get what I wanted.

About two weeks ago, I determined that the fuel and truck note is only 70. 00 more per month. It would have been even closer had I bought the right truck the first time.

tradedv10 , your 98 2500 360 had a 5 spd ??? is this correct ? my 1500 , maybe this is the reason it was a 1500 , with a 360 was only available with an auto , a stick with it would have been nice ...
 
Had a couple 454's never got over 11mpg empty but I had a lumpy cam and a few extra ponies in them #ad
.

Had one 6. 2 GM in 87' Drove from Saskatchewan to Denver with an empty flatbed car hauler... dropped 3 pistons, left the truck in Denver and flew home.

Bought an 88' Ford 6. 9... smoked and smoked up every hill, sucked the fuel with my enclosed trailer and one car in it and I always ended up in 2nd gear on any hill.

Got a 90' Cummins sold it with over 400K on it and it is still running. Had several Cummins Rams for the business and sold em all with over 125K on em.

Bought a V-10 97' 3500 4x4 and it gave me all sorts of trouble. Never got over 8 mpg empty and 3... . yes 3 mpg with a trailer on behind weighing 7,000lbs. Took it to the dealer and all 'checked' out OK. I was not impressed.
Then the keeper for number one cylinder let loose and I had a rattle. LOL
DC put a new engine in but it was a 96 V-10 and it never got over 4 mpg. DC bought it back and GAVE me a 97 3500 Cummins auto 4x4 in exchange. No questions asked and no arbitration!

As for the difference in price of the diesel.
I paid 5250 canadian dollars for the diesel option on the 2001 truck with the ETH.
If I paid 6000 US I would have been bent over for nearly 10,000. 00 Canadian. OW!
The resale of the diesel has a much faster sale and a much higher residual value as well as a far lower depreciation then the V-10.

Check the resale of used Diesel Pick-ups in the Fords and Dodge and you will find that the yr or two old trucks bring almost as much as a factory order new one. Supply and demand dictates this in different areas of Canada and the USA.

Also, if you finance or lease a diesel, that added initial up front cost gets absorbed pretty quick to equate to a small increase in your monthly pmt.

Time to go admire my Great White Cummins powered properly valved RAM! #ad

Mopar-muscle,
That is the reason I got a 2500 instead of a 1500 in the first place. You can get 360/5spd in a 2500, but not in a 1500. Then once I got into a 3/4 ton, it didn't take long until I got the diesel urge!

Basically, the V10 gets crappy mileage. Hot rod it around, and it gets worse. Those are 10 hungry cylinders to feed, especioally when they have been playing hard. The V8's mileage is only slightly better, so it's a tossup between V10/V8. If i had to pick one, I'd buy the V10, just for fun. But I would never do that... I am a Cummins guy all the way. No gas for me. That's why my custome plates are going to say "KIX GAS", still thinking about that though...

BOMBED #ad
 
Altexp, I put almost 200k on a Clubcab 360 with auto. Mostly to work and back and some vacations, towed a 6000# trailer some. Best it would do on gas mileage was about 15 on the highway. The Cummins does about 17 or 18 empty and 11 and 12 towing a 7000# 5th wheel. Looking at the spec sheet on the diesel vs gasoline engine is misleading. I think the 360 was rated at 240 hp and the Cummins was rated(with auto) @ 215 hp when I bought mine. When you start up an incline with the Cummins the rpm's drop into the power band of the engine, when you start up an incline with a gasoline engine, the rpm's drop out of the power band unless you do some serious downshifting. The Cummins will loaf all day at 70 mph and 2000 rpm, my gasser ran 3600 rpm at 70 mph.

I owned a '93 3500 CC Chevy 2wd with the 454 before being converted. I was able to get 11mpg city once. Usually it was mid 10s #ad
Now with the 2K1 3500 4x4 I am getting 13. 4 constantly. With the Chevy I was always worried about what my mpgs were going to be, but with the Dodge it doesn't matter. I know it will be better than the Chevy, and diesel was 15 cents cheaper than gas last time I filled up #ad

Atlexp,

Well my . 02 is DIESEL BABY!! #ad
First Dodge was '95 3500 club cab 4x4, V-10, auto, 4. 10 LSD Loaded. Same camper as now, same trailer, same Jeep. Towing in the mountains (CO, WY, UT) 6-7 MPH @ 65 MPH. Anything more and you didn't need to figure mileage because you stopped at EVERY gas station. Loved the truck pulled like a train but couldn't take the mileage. (was also eating a head gasket or had a cracked head... long story some other time. It was drinking coolant) This also was our only trust worthy vehicle at the time so we depended on it for trips to WI to see family (1100 miles one way) Three round trips combined average mileage was 12. 2 MPG. Me, wife, two kids, two weenies (dautchounds) and a couple suit cases. Also have fiber glass shell.

With the '99 3500QC 4x4 Diesel, 5sp, 3. 54LSD same load bla bla bla... 12. 8 two trip average (800 miles round trip big mts. ) Just the camper 15. 6 MPG average over 1480 miles, Empty (just the shell and us) 19-21 MPG.

You do the math. Go Diesel!!

Later, Bob
 
<font color=green> I had a 86 & 95 Ford 460 3/4Ts 4X4. Both Fords had the same gear ratio 3. 55 and 1 4speed in the 86 and 5 speed in the 95. The 86 actually got better milage towing and empty and was carb not fuel injected. the best I ever got was 14. 6 MPG in the 86 and 13. 2 in the 95. There was no comparison while towing 7-8 MPG taking it really easy and the way I normally drive 4-5. There where hills that I would be in 3rd in both truck moving 30-35 MPH max speed. The first tow with the dodge was incredible and I was still stock I could pick up speed on these same hills and better than doupled the MPG. </font><font color=red> This truck is a keeper!!!</font>
