Gas or Diesel

OK huge question on mind . Frist I am a truck driver for 25 years so I am well aware of the answer to my question but I have never owed a diesel pick up. I am looking to get a 2500 4 X 4 crew cab to pull a 10,000 lb RV around the U.S. The part that I am leary about is the maintanance for the diesel as compared to the gasser

I have a 2500 6.4l hemi and I can say with a fact I have pulled 19,000 and didn't have a problem don't get me wrong that is a bit heavy but it did it well.
If your going to pull something like that get the 4.10 gears on the truck that will be better.

My 94 Cummins is my first diesel but it’s been a great truck. Gas mileage will probably be better with the diesel, maintenance is not much harder, there’s some nuances but very minor. The old argument too was diesel prices were cheaper, but that argument is irrelevant today. I guess it comes down to cost, if the diesel saves you five MPG but cost 10k more, you need to do the analysis of what makes more sense financially assuming you hold onto your vehicles. ie how long would it take you to see the savings benefit.
the diesel also take away LOTS of payload, if you are getting a diesel, get a 3500.
Diesel (after 2008) has the dreaded DEF system. The DEF system in my 2017 Ram 2500 failed me 2x on the road last summer (I also tow a travel trailer). But love the torque and exhaust brake especially in the mountains.

So I had a 2003 Ram 2500 from 2007 until earlier this year. That truck had the 5.9 Cummins and 6-speed manual with the 4:10 gears. I pulled my 16,000lb toyhauler with it no problems, but I did have to add helper springs in the rear to beef it up a touch.
I traded that truck in my my current truck, a 2009 3500 dually with the 6.7 Cummins, 6-speed manual and the 3:73 rear gears. I have yet to get this truck coupled to the toyhauler, but the whole reason I traded the old one in on this one was to move to a more stable dually platform for my big, large, heavy trailer. YMMV since your trailer will be considerably smaller and lighter than mine.

I put a little over 200,000 miles on my old truck, always kept the oil changed, filters, things like that. I would say, with the old truck, aside from the typical stuff that wears out over time like injectors needing replaced, clutch, brakes, the normal stuff, I never had a problem with that truck. I haven't owned the new one long enough to form an opinion on it yet, but it had 212,000 miles on it when I got it and I did have to replace the clutch already (which was not unexpected). But I find these Ram diesel trucks (in the 2nd gen and 3rd gen at least) to be extremely reliable and long lasting rigs and they tend to pull like a freight train no matter what I throw at them.

As for the DEF comment above, I'm lucky that my 2009 is the 3500, which still uses the 2008 platform so it doesn't have the DEF system on it. 😎
That being said, it also doesn't look like the 2009 Ram trucks either, so it's a trade-off I guess. 🤷‍♂️

I've had all long beds 2500s, a 2001, 2005, 2013, 2015, 2018. My 18 is my first diesel. I tow very little with it but what everyone said is true " You don't even know the trailer is back there". That said, it means it's mannerisms are the same as without a trailer. It is the slowest vehicle I've ever driven but pulls the same with or without the trailer. I really like the engine brake when going through the mountains. The DEF is another useless expense however I hardly notice it.
My 2015 had the 6.4. That towed and pulled hard, lots of power going up grades. Fuel economy was horrible but I loved it.
My 2013 was a 5.7 . That engine should never have been in those trucks.
To add to this I've towed mostly car trailers. I've dabbled in travel trailers the biggest being 30 ft. All of those travel trailers were in Wyoming, Montana, Idaho and Utah, so a lot of mountains.

The reason I bought the Diesel is because it came with the CD player. I'm very glad I did. I'm counting on its million mile longevity.

I also have a 94 Ram/Cummins/5-speed. If you are looking for a new truck keep in mind that the 2008 and newer units have the carbon filter/regen cycle (not the DEF system, that came on or about 2011. The carbon filter, if it clogs up, costs, from what I have heard, over 1000.00 to clean. You can't change it. I have also heard of DEF system failures. As a truck driver (as was I) you know that you had better not run out of DEF. The cost of diesel fuel has gone way up, partly because of the new fuel. Unless you really need the higher power/torque of the diesel, can you justify the extra $10000 for the diesel engine? I love my Cummins but I purposely bought an older one that is exempt from all the emission BS. If I were to buy a new truck today and I were paying for it I wouldn't buy a diesel. Plus I prefer the 5-speed to an automatic and they are no longer available so no new truck for me.
The 30,000 mile service on my 2014 Ram 3500 6.7L Cummins last year ran $3,000. They changed every fluid. Engine oil, transmission, transfer case, rear end, brake fluid and I think power steering and coolant, but maybe not, also rotated tires, replaced both fuel filters. It’s an expensive truck to maintain for sure, but you’re gonna be pulling a good load and the diesel is the way to go. The Jake brake is a god send the gasser doesn’t have. I pull a 15,000 lb. fifth wheel. On my 2014, Cummins/Ram requires the oil and both filters be changed every 6 months, 500 hours or 15,000 miles whichever comes first or the warranty is void. Oil and filter changes are several hundred dollars. It may be different now, but I doubt it.
That is exactly what I drive and tow. Oil, oil filter, and fuel filters change cost about $400, but it is 15,000 miles between changes. DEF is a nuisance but not a major expense. I love the diesel for towing. Gets in high gear and stays there without the constant shifting.

It's very true that some maintenance items are quite expensive but remember, you can probably do it yourself or have it done for much less. Federal law allows self maintenance or non-dealer maintenance so long as you have all your receipts. The Exhaust brake is a great addition but you can add one to almost and Cummins for around $1500 or so. They don't make a "true" jake, or Jacobs brake for small trucks because that would require internal engine modifications. I understand that the exhaust brakes are a great addition but as I recall, only the Ram offers it from the factory
Don't get me wrong, I love my Cummins diesel Ram but I think the old 5.9 was a superior engine than the 6.7, especially for someone that really knows how to drive a diesel. I don't like the diesel/automatic combination based on my experiences. I would rather shift when I want to, not when the automatic wants to. Mine has all the power/torqe I need and have been told it's a 500,000 mile motor. I'll never live long enough to justify the cost of the newer trucks. I know that the DEF system does some good things. The air coming out of the exhaust is probably cleaner that what goes in but it's just another layer of complexity I can do without.

I have a 2017 2500 limited 4x4 mega cab with the 6.7. We pull a 40-foot 5th wheel travel trailer. I love it. The exhaust break is wonderful. Helps save on the truck breaks. I change the diesel and oil filters myself. And rotate the tires myself, and I am 74. Everybody talks about the expense of owning a diesel. Me, I haven't seen it. This is our second diesel. Our first was a 04 3500 5.9. The engine was great, but that was the most uncomfortable truck that we have ever own. For me, towing anything long distances, I would not own anything but a diesel. Just my opinion. And you know what they say about opinions, they are just like a__holes, everybody has one.

Thanks I got that same info you spoke of friday I went to the dealer and saw a power wagon I think that is the truck for me so thanks agian

I'm still stuck on the part where your 2014 only has 30,000 miles! 😲
My 2003 had 258,000 when I traded it in a couple months ago on this 2009, which had 212,000 when I got it.

I own a 8 month old 2022 Ram 3500 Mega Cab with the HO Cummins. I'm at almost 6,000 miles and just today I checked my dash readout and it is showing I'm at 60 something % on my fuel filters and I had the thought wonder what the service will cost me so I called my local RAM dealer. He quoted me just under $200 for an oil change and just under $400 for fuel filter change.
I changed my own oil myself at 4K miles to get the break-in oil out as I'm old school. I found some clearance Rotella T5 10w -30 at Walmart for I think around $12 a gallon and around $20 for a Mopar filter so around $60 for a DIY oil change.
The dealer I purchased my truck from actually offers lifetime free oil changes but he is about 1.5 hours each way so I may just change my own oil; This is my first diesel truck so I need to watch some videos before I know if I can change the fuel filters myself.

I wondered about the $$$ of the diesel service like you but then had the thought if I can afford the truck I guess I can afford the oil changes. I'm thinking the resale, long engine life may make it worth it but I wanted the diesel so thats what I got and Im glad I did.
I will say that I love my big diesel truck and I am amazed how many people will tell me how nice my truck is.

I haven't changed the fuel filter in my 94 Ram/Cummins yet but on my Ford with the 6.9 diesel the best way to change the fuel filter was to release the pressure, remove the old filter, fill the new one with diesel fuel, install it, and don't be surprised if it takes a little cranking to get it it run. Remember that the fuel system is under high pressure so bleed it first. It can do harm. Then sometimes it takes a little while for pressure to build up again. If you need access to a service manual they are normally available on the web. The only problem is the manual for my truck is over 1800 pages so I didn't print it out.

Just remember when looking at the powerr wagon. It probably isn`t the best choice for towing. It has a much softer suspension for off roading. The payload and max tow numbers aren`t much better than a 1500.

Isn't the fuel filter located along the frame rail somewhere? I had to have mine changed on my last truck because when it started getting clogged the truck stopped running due to low fuel pressure at the injectors. I just paid my guy to do it back then. It was weird because I think i had to have it done on that truck at about 100k, but then I put another 150k on it with no issues at all. Vehicles are weird. 🤷‍♂️
Not sure on your 09, but on my 2017, it is on the driver's side of the engine. You get to it from the top. Then, by the rearend, there is a water separator. And then behind the passenger front tire is the oil filter.
