Cab/chassis vs standard DRW

But 5 pages later, does it actually matter?
OP has the truck, the flatbed and the camper. Either it is a good setup, or not so much. All minutia at this point.

Difference in frame design is why it would be good to know if the vehicle is a pickup with box delete ot is a true cab and chassis.

Do Cab&Chassis trucks weigh more than standard DRW trucks (all other things equal)?

I bought a 2021 3500 Chevy DRW cab/chassis gasser, crew cab, 4x4. The stated payload on Chevy's website for an "equivalent" gasser (3500 DRW, crew cab, 4x4) is 6610 lbs, stated GVWR is 14,000lbs.

Since my vehicle is "incomplete", can I assume the same payload (6610 lbs) plus whatever the weight of the "deleted" bed would be on the equivalent 8ft pickup, minus whatever flatbed I installed?

In practical terms, I have a Hillsboro GII steel bed that weighs 1230lbs. If I assume that the 8ft DRW bed weighs 500lbs, can I do 6610lbs + 500 lbs - 1230 lbs = payload of 5880lbs on my cab/chassis equivalent?

Thanks!

So back to OP's question - I'm almost certain the pickup with bed deleted will be lighter than a CC, assuming same engine, options, wheelbase, etc.

A boxed frame is stronger than a C-channel pound for pound. Their shape is also easier to optimize to squeeze out more weight to strength ratios. With a c-channel, you have to be straight and uniform in cross-section for up-fitting.

Thank you. This is my impression as I cannot explain the difference in weights/payloads.

I was told in Virginia you have to register for max GCW you intend, so went with a large number (25000lbs).

Your state as other members have reported their state use a GCW number for registration purposes. Thats the number you can't exceed while pulling a trailer in your state. And of course you can't exceed your vehicles axle/tire load ratings which is generic in all states.

Now what weights does your state use for a overloaded vehicle. You get all types of opinions on a rv website so what I do and recommend is drop by your local state troop post and ask their size and weights enforcement officers that question.

While some other states as you see have some type of tonnage/gvw or that type of weight to use for registration purposes. Seems like folks from these states think all states are the same ....when their not.

Or like I said above my state as other members have stated have no weights for registration purposes (non commercial vehicle).

ogned,

ASSUMING you are under all of your warranty weight ratings, you will not have any issues I am referring too! "ON THE OTHER HAND" if you pushed those warranty weight ratings to the true max legal ratings, you would have the painful $$$ issues I am referring too to Ron, ie cummins12v.

My F3 fitty cab and chassis has straight, flat frame rails 34” wide as per SAE standard, same as class 5-8 commercial trucks.

It had a Max GVWR door sticker “with such & such tires”.

As mentioned a “second stage body builder” or “upfitter” engineer can change the weight ratings within component guidelines.

You mean other than the very first sentence of the first post where he says he has a C&C truck? Lol

Correct Ron.
OP can probably run down the road based on what he says his registered wight is at 16-18000 too. At least here, that would be the case. Even 25000 for that matter. Not that any one with a typical 35 series dually should be at 25000gvw. Wieght won't be issue. Some law rule etc will get them off the road. It will be a painfully $$$$$ lesson.

Marty, I am not sure what you mean by your remark on "Some law rule etc will get them off the road. It will be a painfully $$$$$ lesson". I plan on running a Palomino HS-2902 Max truck camper (3261 lbs dry weight, probably 4200 lbs wet) and towing a 2-horse bumper pull trailer at the same time (loaded about 6500lbs). I was told in Virginia you have to register for max GCW you intend, so went with a large number (25000lbs).

Before I went with the current truck camper/bumper pull setup, I had some plans on buying a horse trailer with living quarters - these usually come in at 13-14,000 lbs - plus loaded weight of truck (9000lbs) - I would have come in at 22-23,000lbs max (hence I registered for 25,000).

Either way I am not over GVWR, not over GCWR, not over RAWR and not over my registered weight... - how would I learn a "painful $$$$$ lesson"? Thanks!

I am the OP - I have a crew cab 4x4 cab/chassis Chevy 6.6L gas truck.

p.s. The Chevy equivalent page to the GMC lists available payload as 5,751–7,040 lbs (https://www.chevrolet.com/commercial/silverado-3500hd-chassis-cab)
