Fell in love with the Host Mammoth Truck Camper. So am in market for a 3500 DRW - my 2500 Mega short bed has been great but it will not hold the BIG camper.

I was all ready to get the Cummins but then realized I might be happier with the 6.4 gasser - more payload.

Any thoughts?

"The F450 pickup is rated at Class 3 levels so insurance and licensing does not bite you. "

I have real many reports of higher insurance and licensing with the PU F450.

So if the F450 grosses at 14K like a class 3 truck, yet weighs quite a bit more, then does it not have a lower carrying capacity?

Nope, you completely missed the point. The F450 pickup is rated at Class 3 levels so insurance and licensing does not bite you. Once you get to the chassis cab Ford F450 and F550 or Ram 4500 and 5500 is when you start paying more due to the Class 4 and 5 classification and lack of a pickup bed.

Along with that comes higher insurance and licensing.

Not sure but I carry/tow more weight than MOST anyone on here with ZERO issues with a measly 3500 Dually. At a much lower cost than a comparable F450.

You can buy an equally-impressive new Chevy Duramax too.

If we're only talking engines, I'd agree with you. All three manufacturers are extremely competitive in the impressive numbers put down.

But lets talk about the rest of the truck. An engine alone won't get you down the road hauling a Host Mammoth.

What do Chevy and Ram offer that compares to the F450 CCLB?

10 lug axles?....nope
G rated 19.5" tires?...nope
Wide track front axle with tighter turning radius?....nope
Front suspension components from a class 4 truck.... nope
Bigger brakes?....nope
16k lb rear axle?....nope
Better tow mirrors? ....nope

Lol! You guys crack me up... you'd tow with a Yugo as long as it had a Cummins in it.

I guess my point to the original poster, is that there's more to the job of hauling a big camper than simply which engine is in the truck.

I agree 100% that if he's dead set on going Ram, the 6.7 is the way to go. Ignore the additional payload the gasser offers as it's meaningless to your rear axle weight when hauling big campers.


Well if you compare apples to apples the f450 isn't in the class with the 3500 Ram, even though ford tries to put it there...try comparing to the 4500 Ram and you'll get the heavier stuff you list.

That's it? That's the only pro you could come up with for the Ram hauling capabilities over the F450? 😄

Shall we bring up Ram tie rod ends?? 😉

Which would you rather have fail with a 6000lb camper and your family in your truck?

Great! You got the right type of engine, now you just need the right brand of truck.

Ford makes the perfect rig for the Host Mammoth. The 2015/16 F450 has a long list of advantages over the Ram 3500. Stronger Axle, better gearing, tighter turning radius, G rated tires, more power, quieter ride, lower bed height for easier camper loading, better tow mirrors, stronger factory hitch, bigger brakes, front suspension components from a medium duty truck....you get the idea.

You get the benefits of a medium duty truck without the penalty of a derated engine.

It's all about buying the best tool for the job.



Why Ford...Ram makes capable 4500 and 5500 series trucks with the Cummins/Aisin combo!!




Why Ford? Didn't I already answer that in the post you quoted?? You get all the benefits I listed without the penalty of a class 4 truck...the Cummins/Aisin combo in a 4500/5500 is derated to 325/750 (that's 115hp and 150tq less than the F450!)...and then you have to put a flatbed on it.


Look I get it, the original poster is dead set against a Ford Diesel due to a problem with an engine built a decade ago, but that doesn't diminish the fact that the 2015 and up F450 CCLB is setup the best of any class 3 truck to carry the biggest campers.

In the real world - not brochure fantasy land - the diesel will out-haul the gasser every time. That's the fact, Jack.

As one who was on the "gasser" side of things on this thread, and a person who has owned and towed with both, I have to say I agree with you. From a performance standpoint, when towing or hauling, the diesel will do a better job 99% of the time. That's where they shine. That doesn't mean the gas engine won't do the job though. If that 8 or 10k price difference matters to the buyer, and they are looking to haul a load infrequently, the gasser is a great option IMO.

So is the notion that you need a dually with a wdh and sway control to pull anything bigger than a popup, but that's how we roll here!

Of course I make my back tires scream "We wish we were duals!" So loud I have to roll up the windows sometimes! Lol
