Gas vs Diesel engines.

I currently have a 2006 Dodge Ram 1500 HEMI with 51,000 miles and tow a 6,800lb TT with ease except hills. I get 8-10 MPG while towing and was wondering if I would get better gas mileage from a diesel engine. Also would the cost of buying a used diesel 250/2500 or 350/3500 2008 or better with 50,000 miles or less be worth it? Should I go by the old saying if it ain't broke don't fix? My wife thinks we should get a used pontoon boat instead of new tow vehicle.

My wife wants a pontoon boat too, but then I'd have to get a pickup to tow it and she would have to drive it to haul the boat. Don't want to use a 41' MH to launch a boat and the MH won't float!

You'll get significantly better mileage with a diesel but even so you'd have to drive a lot of miles to pay for the upgrade. Unless you are in an usual situation I doubt it would be worth it strictly on a financial basis.

I have a 2500 GMC Duramax, tow at least half again what you do, and get 10-11 MPG in the hills and mountains. On "flat" terrain like Florida, I may get 12-13 if I keep my speed down. On average I'll call it at 11 mpg towing. Empty I'm at 19-20.
Accordingly, I ain't doing much better MPG, but I don't have trouble on grades and easily pass most gassers towing even lighter loads.
The down side is fuel is a little higher and the diesel "option" is several thousand bucks. In my case it was about $7k. Of course, given the same conditions, a diesel will out last a gasser 99 times out of a 100, and they pull like a mule.

I have towed the same 5er with both a gas engine 6.0L Chevy 2500HD and a 6.7L diesel Ram Cummins 2500HD Mega Cab. To me it is like night and day between towing with a diesel and a gas engine. If I could not afford a diesel engine equipped truck in the future I will give up camping. I will not tow with anything else in the future. My gasser would only get 6 to 7 miles to the gallon towing the 5er on flat land. The diesel will get 11 MPGs on the same flat land and in the mountains I normally see 9 to 10 MPG. The truck is working harder and burning fuel but you and the passenger would never know this unless you look at the boost gage and RPMs to see what is happening.
In fact my wife has switched to a diesel car also for better mileage; she drives a VW Jetta TDI.

I'd stick with what you have if it is in good reliable condition - Just my 2 cents, buying a used truck to save a few $$ on fuel (while towing) is introducing a lot of reliability risk for a little long term gain on fuel cost.
Your 7 year old truck has 50K miles. Ask yourself how much of that is towing - you might not drive and tow enough to break even.
I'd go with the boat.

At an average price of 7,000 more for a diesel engine, and the increased cost per gallon over regular gas, you will never realize a profit from the mpg savings. Stick with what you have and buy that pontoon boat the wife wants. Keeping her happy means miles and miles of stress free driving, not to mention relaxation on the lakes....

I had the Ford V-10 and went to the DRW diesel (350 crew on both), night and day difference in towing, I also get better fuel MPG now empty or pulling. I am happy I changed but... if I was not in the hills or even less hills I probably would have saved the money and stuck with the V-10, especially if it meant another TOY.
If you are not unhappy with the performance stick with what you know.

Thanks to everyone who responded! I have removed the for sale sign and started looking for pontoons.

I totally agree that a diesel will out pull a gasser. I in fact, there's really no comparison. I had a neighbor who drove the wheels off his F 250. He had over 235,000 on the clock when he sold it. He told me that he just loved the 7.3L in it. The problem with diesels is that they will outlast the truck. He needed assorted front end steering parts for the second time. He also replaced the rear and tyranny. The interior was shot and the bed had it's share of rust along with the frame rails and rear shackles rusting through. From what he told me, the engine will keep running long after the rest of the truck is worn out. He now drives a 2009 F 250 gasser.

I towed with gas powered trucks for years - now I have a diesel. As far as towing goes the diesel wins hands down. It is like night and day. The diesel seems to be built to tow. But diesel engines are more maintenance. If you do not tow far that gas engine is fine and a pontoon boat is in your future. If you tow far - then the diesel is the way to go. FYI - I would expect a diesel truck pulling your current trailer would get 12 - 14 MPG. You would also notice a big difference towing up mountain.
