When we hired the trucks to haul we used the registered weight to determine the amount we would load on them. Overloaded trucks were not allowed out from the scales.
MH are not like trucks so I doubt anyone actually checking to make sure the RV owner is using the rig within it recommended guidelines.
Good points and right on
RV forums are a hoot when it come to the different opinions on legal weight issue. So much useless comments get posted by folks that have never been there.
I've got over 800k mile in a 11 year period using 3500 SRW/DRW trucks. Legal issues for determining how much load a truck can carry is determined by the trucks FAWR/RAWR. And of course tire load ratings which will have to be equal to or better than the GAWRs.
I think California says it best with this;
eclared Operating Weight
What are GVW and CGW?
3. Q - Can I declare an operating weight higher than my vehicle's Gross Vehicle Weight Rating (GVWR)?
A- Yes, but only if you are declaring the weight of your vehicle in combination with a towed vehicle and its load (the Combined Gross Weight). NOTE: A declared Combined Gross Weight does not authorize a truck without another vehicle in tow to exceed the truck's authorized axle weight limits. "
And another example from the California motor vehicle enforcement side;
Q: “Many of the owners travel over their tow vehicle GVWR and /or
GCWR. Are there any state laws against this? Or does the owner just
take the risk if they wish?”
A: The California Vehicle Code (CVC) does not contain a law that
specifically limits the amount of weight a vehicle may tow based on the
towing vehicle GVWR or GCWR. There are, however, laws that limit the
amount a vehicle may tow based on other criteria.
Section 1085(d) of Title 13 California Code of Regulations prohibits
the loading of tires above the maximum load rating marked on the tire,
or if unmarked the maximum load rating as specified in the applicable
Federal Motor Vehicle Safety Standard, or in a publication furnished to
the public by the tire manufacturer. This would most likely happen in
the case of a pickup truck towing a large fifth wheel travel trailer, as
those types of trailers tend to transfer a larger portion of their
weight to the last axle of the towing unit causing that axle to exceed
the tire load limits.
Regardless of info posted on a RV forum were all hauling legally under the same weight regs between all the states.
Some state require a private use truck to be registered at some type of weight. Other states like mine have no registered weight. We simple carry weight determined by the lessor of the vehicles axle/tire load rating.
Now the OPs question about a 4500 lb dry camper and a 6000 lb tow rating deserves a answer .
The first sign could be a bit sluggish towing performance especially with the smaller V8 and V6 engines. The newer gen 375-400 hp small blocks not much at all.
Trucks 20-30 years ago had small radiator capacity and could run hot .None of those issues we have today.
IMO TH OP is needlessly concerned about those numbers being a over weight condition.
