    Either is fine with a 6 speed on the freeway. Only 1st gear is really effected. And I'm really gentle on the truck in 1st gear. (master tech, so I know what happens when you stomp on it)

    The 3.73 in 5th gear, is about the same as a 4.56 in 6th gear, and so forth for the 3-6 gears. 4.10 and 4.30 are somewhere in the middle. Stock tires and 3.73 is perfectly fine. In some cases the 3.73 is superior. You'll have more power in 3rd gear with 3.73, than 4th would with 4.10's. Getting going in 1st gear is the biggest difference, and a 6.7L DRW ain't going to have trouble with that.

    But if you want beastly tow ratings, get the 4.10. Unless the E-locker is truely available for the 3.73 truck. I didn't think the DRW's could get the OEM E-locker at all.

    Here's the #'s from a 3.73 vs 4.30 gasser argument, for example:
    2nd is 2.31 3.73= 8.62 4.30=9.933
    3rd is 1.51. 3.73=5.63 4.30=6.49
    4th is 1.14. 3.73= 4.25 4.30= 4.90
    5th is 0.87 3.73=3.24 4.30=3.74
    6th is 0.69 3.73=2.57 4.30=2.96

    Since a gear lower with the 3.73 is much higher rpm than a gear higher with 4.10, you might find yourself needing to slow down a little bit on hills. No big deal.

    I had 3.73 in my 2011 Ram. No issues but I do like the 4.10 in my 2016 Ram better. I just ordered a Ram 5500 with 4.44. I will be hauling the same Host on it. I got the 84 inch Cab to axle so will have a 11.3 foot flat bed on it. I am looking at builders of aluminum beds.

    zb39, why the truck upgrade?

    You could check out camperlogic.com they have a build thread in the earthroamer etc just above this one. It is aluminum and looks really well thought out and designed to carry a camper on the back. I am not sure if the typical off the shelf aluminum flat bed like CM or Hillsboro could take the weight and twisting having a camper loaded onto them.

    I want the ability to customize my storage and bring more toys. I also have a new 8.5 x 20 enclosed trailer I want to haul on some trips. I just like everything to be over built. I go to the Knob Creek
    machine gun shoot every year. I want to load my guns and ammo and my Kubota RTV in the trailer. I don't want to be at 16k with a 14k GVW. I will also be flat towing a new wrangler behind on different trips. Also I want to go back to Alaska and go to some places I couldn't when I was in my 40' DP towing a car.

    I should also add that I have 6 batteries and a 4k PSW inverter that powers the whole rig including the electric fireplace or the AC, just not at the same time. I also haul a 2k Honda. So I added 500lbs to my heavy camper. I ordered my Host to get what I wanted. It does weigh 4200 lbs empty and dry. I checked at the scales 10 minutes after loading it the first time. But 65 gal of water is 520 lbs and my batts and inverter are 498 lbs. So I add a 1000 lbs. Thats 5200 plus food and clothes, tools. My truck is a Laramie Limited Crew 3500 4x4. 9300 lbs with full fuel and DEF and TL frame mounted tie downs and fast guns,and 2 people, I scaled it. Figure 400 lbs for food and clothes. That puts me at 14900. Not bad, 900 over GVW but way under my axle ratings and way way under my factory tire ratings. But then I add a trailer, or I go to Knob Creek with out trailer. Tried once, I was 16k without water. Had to off load a bunch of ammo. The 5500 will just be better for what I do and I will be more comfortable with it.

    Since it's a dually, it probably won't get big tires. The 3.73 gears will have plenty of power, wherever you go. But....
    If you ever plan to sell it, those shopping for DRW trucks usually look to have the highest tow rating they can get- that means the 4.10 gears would make it more desirable on resale.

    I sent them an email. They look awesome but the price was way over my budget for just the bed and boxes. Over 22K.....But I'm sure it was very nice and built well.

My mammoth will be delivered in January.
    I just picked up my camper weighing 5k with the upgraded rims and tires, it didnt miss a beat. 3,73s are fine..

    zb39, good points, im considering upgrade as well the insurance costs for anything above 3500 are holding me back.
