Should I get a 2020 GM 3500 DRW or a 4500?

Well it is getting to be New truck time again.
First off, I am not married to any brand. I have owned them all at one or more points.

That said, The Rams and Fords did not make the cut this time around.
You may disagree, but it's my money, and my rules as to what I will base my standards on.

I was thinking of a GM 4500, but moved away from it, as the overall length would make some garage modifications necessary. And the fact that it is not available with a factory bed like the F450 has. So an aftermarket one of some sort would be needed. The costs seem to vary wildly on these.

When I started reading about the 2020 GM 3500 DRW, it checked off a lot of my boxes.

Then last night, I saw the overall length spec.
A tape measure of the garage confirmed my suspicion. It has grown enoughto require pretty much the same garage mods as the 4500.

So that part of it being a tossup, has me on the fence now.

4500 pros: tougher truck all the way around.
Wide track front axle, for tighter turning radius.
Available now.

Cons: Not sure about the insurance situation. Are they typically insured as commercial? Or is it just another vehicle on my private policy? This may vary with the state and the company. I am in AZ, and curently with Gieco.

Probably a much harsher ride.

The next one could end up in the pro collum.
The aftermarket bed. What do you have? What do you like/dislike about it? Cost?

The niceties are just not as nice.

The tranny. There are several options available. I simply do not know enough about them to decide, which one would be for me.
This too could possibly end up in the pro collum.

3500 DRW pros:
Very nice in the High Country trim. Features such as the virtual trailer camera system are a game changer.
Upgraded capabilities would be more than enough.
10 speed tranny is likely a plus.
Can pretty much nail down the price now, since the bed is included.
Same thing on the insurance.


Cons: Not as stout as the 4500. This may be a long term durability issue.

Not available now.

That is about all I have thought of so far.
Would be interested hearing others thoughts. Especially from those that have already made the decision either way, and what they have learned since.

Oh yeah, a new 5th wheel TH in the 20-24K range is in the future.

  • I see the big flop with GMs 4500 being the position of the DEF fill. ”Smartly Postioned” as GM puts it on the passenger side front fender.

    Every truck stop in the country has the DEF fill nossel on the Driver side.
  • Huntingdog, if you are tagged in AZ. make sure to call your insurance agent first!

    The big question you didn't answer is: What are you going to use the truck for?
    I have pushed my '05 Chevy dually well past it's GVWR numerous times with both my TC and my work. I often have the truck's axles supporting over 12,000 pounds while pulling another 14,000 or so pounds. It's done well but I always figured the next truck would be a 4500 and I was excited to see Chevy make them again. But, a new 3500 is so much more capable than my '05 that with my same weights I would be within it's ratings. I've sat in a 5500 and while really nice it is also really tall. I wish they had kept them low like RAM and Ford did, basically still pick-up height. The big problem with the tall cab is that it would be nearly impossible to use it for a truck camper. You would have to raise the camper up to clear the tall cab. That's not something I really want to do.
    As for the bed, I run a flatbed with boxes above and below. Previously I had a utility body with storage. Both of these are for my business use but they worked out great with TCs too. I had plenty of storage for tools, fluids, cord, hoses, camp chairs, etc. even with the TC in the bed.
    If you want to pull a FW a nice hauler bed would give you lots of storage and make hitching and unhitching the FW real easy.
    The real kicker is they lowered the HP and torque on the 4500 and larger trucks. They are still incredible powerful but not absurdly powerful like the 3500.
    I've decided my next truck will be a 3500 ordered with no bed so I can have a new utility bed put on it.

  • Here's the main reason I'd avoid the 4500 for now: Service

    This truck being a joint venture, will have some parts designed and/or supplied by Navistar that won't be in the regular GM pipeline. Or might not be covered in the GM repair guides yet. And GM has a history of rolling out other joint venture vehicles without having enough techs trained initially.

    Ford was formerly in the same boat with the F650, before pulling it away from Navistar. Getting work done wasn't always a pleasant experience, and Oregon only has one dealer certified to work on the "Blue Diamond" (the joint venture name) F650/750 trucks.

    Also, it probably won't ride as well, since the 3500 likely has a much stiffer frame, especially torsionally. While the MDT frame are strong, they tend to be a little floppy so you feel more judder.
