With those suspension upgrades I think the new able would be an increase in CCC.

IMHO I also believe the addition of suspension upgrades, listed by Scarecrow; which I also had done on my 2014 a couple of months after purchasing my rig, increases the load carrying capacity of the rig. The only thing not addressed by these upgrades is "breaking power", so over-loading does reduces the ability to safely stop the vehicle in a potential crash event. Knowing this I drive "55 to Stay Alive" when ever on the interstate and freeways, and always in the right lane whenever possible.

So do I. But those more knowledgeable than I say none of them matter because CCC is directly determined by the chassis design, and nothing you add can increase the CCC. I'm sure those members will jump in here in just a few minutes... waiting... still waiting... they must be sleeping...

I think one of us should field test this. Load up about 10,000 pounds of stuff, drive a range of roads and conditions, and report your findings to the group. =-)

That brings up an interesting point. I wonder how they determine the CCC of the initial configuration? Much less when any alterations are made? I did buy the Kindle version of the Federal Record on this. But it will take several rum toddies for me to sit still long enough to read it.

You dont have to pay to get a full copy of the FMVSS.

Just go to this government web page and select the PDF download on the left side. That will give you a 881 page document of the entire PART 571—FEDERAL MOTOR VEHICLE SAFETY STANDARDS. Then you can just search the document for current info on weights and OCCC labeling.

https://www.govinfo.gov/app/details/...9-vol6-part571

Edit: The applicable info is in FMVSS 571.120 Tire selection and rims and motor home/recreation vehicle
trailer load carrying capacity information for motor vehicles with a GVWR of more than 4,536 kilograms
(10,000 pounds).

I did not see that link before buying the Kindle eBook. Ah, well... thanks for the feedback!

Default Re: Are RV Manufacturers Required to State the Empty Weight of their RVs?

The mystery to me is how the RV is rated for a maximum carrying load. I assume the marketing people at MB in Germany decided they wanted to target a small truck segment, and picked a GVWR they thought would cover most the target market, without taking market share away from the bigger diesel trucks. Then the RV manufacturers started looking for a chassis / motor platform that would match the market segment they wanted to build for .. i.e. Class B+ and Class C. The whole issue of CCC is the net result CVWR less the weight of the stuff the RV manufacturer loads on the truck platform.

My point is the target market segment MB choose to compete in with the Sprinter Chassis requires a certain amount of carrying capacity; which did not necessarily meet the RV market needs. I am sure the design of the Sprinter frame, brakes, power train, etc are all over the minimum required to meet the CVWR. How much over?? Ford and GM both have touted in advertising for their trucks that they are far exceed any and all government standards; which I assume also includes the CVWR of the trucks.

Also since it has been reported in the Federal document listed above that over 50% of the RV's and Trailers ( both commercial and recreational ) are over weight by a factor of 20% and there does not appear to be a lot of press about accidents caused by over weight vehicles.

You are correct, nothing you can do will change the official/stickered CCC of the vehicle.

In real world terms you would have to find the weak link that causes Mercedes to limit the GVWR to 11,030, I do not know what this is. Could be tires, rims, axles, frame, etc.

Many factors go into this, Scarecrow, although you made suspension improvements that surely improved your ride if the total weight of those improvements are more than the original parts you replaced then you officially lost some ability to carry cargo because your CCC did not change.

Weighing the vehicle is the only way to see if one has exceeded the GVWR.

Nothing you have done will increase the capacity rating of the vehicle. Check out the fine print on websites for all your "improvements".

The things that stop the vehicle are Brakes, not Breaks. (I am a sometimes believer in the if you cannot spell it, perhaps you should not make statements on the subject)

Any increase in weight of the extra stuff you had installed comes out of the CCC.

As others have stated, is is possible to decrease the capacity by installation of inferior tires.

There are freeways in America where driving 55 puts yourself and others at risk by jamming up the flow of traffic, and causing more opportunities for crashes in the otherwise unneeded congestion. there is a place for keeping up with the flow of traffic. Best schedule your travel in these places for off-peak periods if you insist on driving overloaded and want to crawl down the highway.
