Gassers: Ram 3500 6.4L vs Ford's F350's 6.2 and 7.3 Godzilla for overlanding

Ram hd seems to rate high in owner’s satisfaction and reliability compared to the others. Just driving around on a dirt road probably tough to feel the difference between 6.2, 6.4 and 7.3. No one ton truck is going to be even a mild/ medium rock crawler (think rubicon trail type stuff) without extensive work. I have had my power wagon to moab and does great on dirt roads but would fail at truly offroad stuff Unless you wanted to beat the crap out of it.

What are the gearing options on the Ram 3500? And IIRC doesn't the one ton ram go to leaf springs rather than coil? Does it offer factory locking differential? How large of a fuel tank is available?

I'd go Super Duty just for the aluminum body for maximum lifespan without dealing with body rust. An investment of this price (I'm guessing 60+ thousand USD minimum just for truck) I'd want it to last. They also have a minimum of 34 gallon tank here in Canada in configurations I've looked at.
Super Duty gives option of 3.73 and 4.30 gearing from factory and rear locker, which will make more of a difference off road I'd think. 6.2 in 4 low with 4.30 ratio would have plenty of torque in most cases. Montypower has a camper on a super duty with 6.2 and 37s and doesn't seem to be having any problems.

I am of the same opinion which is why I want to tailor my suspension to hauling a camper. The thinner sway bars on a Tremor for off road articulation are literally the opposite of what you want for a slide in camper with a higher CG.
Even without off road modifications, it should be fine on dirt roads.

No personal experience...but I have a close friend that bought the Ram with the 6.4 Hemi in it three years ago. She is already closing in on 70,000 miles on it, and most of that is with a horse trailer in tow. She reports no problems at all, only routine maintenance and a set of tires.

I would bet all 3 of these gassers will get about the same mpg when running the same conditions. I am amazed at how good my 6.4 gets considering I had read they were gas hogs. Even on winter gas it is doing great.. I have no doubt a 6.2 or 7.3 is getting close to the same +- a smidgeon.

I have a 6.2 with the 6 speed in a 2015 f250. Still surprised how well that engine pulls. But, I've never ever thought "I bought too much engine in that truck" I'd go 7.3 if it's not too much of a difference in cost. Doubt you'd go wrong with any of those choices as far as powertrain is concerned.

My wife and I are debating full size platforms for a flat bed (short bed) camper with international travel in mind. We've narrowed down selections to Ram 3500 and F350 gas engines due to payload and fuel availability everywhere. There will be some highway travel involved and lots of off road touring, some mildly technical but not seeking overly technical rock crawling tracks per se. I would love opinions and examples regarding:

1) reliability of the engine / transmission combos
2) off road capability engine / transmission-wise
3) off road capability suspension / angles (approach, departure, brakeover, turning)
4) International serviceability
5) MPGs in hauling but not towing conditions
6) If Ram, would you consider AEV, if Ford would go with the Tremor?
Now that Ram finally has an 8 speed, for real overland use the powertrain itself is not even a factor. They only become important towing a 10k lbs travel trailer.

Tailor your choice based on which chassis you want, and just take whichever motor comes with it. They're all very good, and miles ahead what was available 20 years ago.

Trips around the globe has been made with engine half the power of a Ford 6.2, at higher GVW.

In December I placed an order for a 2021 RAM 3500 RCLB 4x4 so you may be interested in reviewing some of my decision making. Although GM and Ford have nice offerings also, I selected the RAM platform primarily because of the AEV suspension and components available. My goal here is not to ignite a debate regarding suspensions but to the best of my knowledge there is not another single company who engineers and tests their suspension and components to the same degree using OEM test criteria and facilities.

Here is one of the videos that sold me on the AEV system:

With the AEV / Ram partnership, I'm assuming no warranties are voided? Did you order through your dealer to coordinate with AEV or AEV directly?

according to AEV yes unfortunately some of the warranties are voided. It is the fine print. Now what warranties those are is hit or miss but if you are running 40" tires most of the drivetrain could be affected. who knows what a dealership would say about the new dash if there were electric problems. any suspension parts would be covered by AEV but not RAM. Driveshafts on a lifted rig most likely no covered.

When I talked with AEV they mentioned that if their system was installed by them or one of their certified dealers the standard vehicle warranty remains intact. If you order individual components and install them yourself each components qualifies for it's own one year twelve thousand mile warranty.

My personal experience is that AEV go above and beyond to take care of their customers. A few years ago I called them with some questions regarding components I purchased in 2001 and following a brief discussion they had over $1k worth of components heading my way the next day. My plan is to have my new truck delivered to AEV directly and have them perform the work since Michigan is not that far away and I have family in the area.

better read the warranty because they clearly state the following.
7.Chrysler/Jeep Warranty. Chrysler/Jeep’s warranty is the primary warranty on all AEV vehicles. Please refer to the current Chrysler Jeep Warranty Guide for more details. Installation of AEV components may void certain aspects of Chrysler/Jeep’s warranty.
