3170ds ccc

Just picked up my 3170DS and I'm confused with the CCC. It has a GVWR of 14,500, and a dry weight posted on the door of 12,448, but lists the CCC as 1495. I would think it would be 14,500 - 12,448 = 2052. Also it has a note that the weight of the full water tanks is 387 lbs. If that were removed it would still be 1665 lbs. Any idea why the differences?

Here is information on my weights. Remember you should not exceed 14,500 lbs (GVWR) on a Ford E450. This is your RV's loaded maximum weight. Also your (GCVW) is 22,000 that includes your loaded RV weight and tow vehicle also loaded.

One thing you can do is weight your RV now before you transfer items. Just calculate the weight of existing fuel. Also get out of the RV and off the scale if possible or subtract your weight. This would help to determine a more accurate ccc.

I drove my #3051S (over cab bunk) to the Truck Scales at the Pilot here in Fort Myers.

Outside TV, 4 door refrigerator, levelers, tow bar removed

Specifications:
(2) Adults (165lbs & 180lbs)
(1) small doggie (12 lbs)
2/3 tank of gasoline
1/3 tank of fresh water (122.17 lbs)
full propane tank
Compartments full with normal camping gear
No Tow vehicle

Certified Automated Truck Scale
steering axle: 4680 lbs
drive axle: 9680 lbs
trailer axle: none
Gross weight: 14360 lbs (GVWR is 14500)

Note:
I will be towing my Toyoda Tocama pickup during my trip. There will only be one adult instead of two. Some cargo will be transferred to its bed for travel. Hitch on RV is rated at 5000 lbs. My Blue OX tow bar is rated at 10000 lbs. (GCWR is 22000) this means both RV, tow vehicle and all cargo.

That CCC was listed on the brochure? or the yellow sticker on the door?

Yellow sticker is supposed to be "that" particular unit. We weigh each and every one. It spits out that sticker and we put it on the door.

That is the CCC on the door. The math doesn't add up unless it assumes full gas, LP, grey, black, and clean water. Is that possible? I thought the dry weight was LP, gas, and water.

The discrepancy is fuel. Our scale/UVW shows the exact weight of the unit that is sitting on the scale. That is the UVW. The cargo carrying capacity is what is left after we add in the weight of a full tank of fuel.

When they put it on the scale they punch in where the needle is (1/4 tank lets say). Then the scale lists the weight of the unit (UVW). Then it subtracts the UVW PLUS 3/4 tank weight of fuel to give you the Carrying capacity.

Another note. We use diesel and gas. So apparently corporate is taking the average of the two to figure the weight.

However, I'm glad you brought this up...cause its still off. We tell corporate we have a 12 gallon LP tank assuming that they will factor the 80% capacity. They are not. They assumed the tank size allowed for capacity...but the tank is stamped with water capacity (not the 9.8 gallons of LP capacity). So we're already overestimating there. Then we're figuring "near diesel" weight for a 55 gallon gas tank. After all that I still can't account for another 100 lbs of overage.

I'm still a little confused here. If the dry weight of the vehicle is actually 12,448 lbs, if I add a full tank of gas at 208 L that would be 337 lbs. Then if I add 42 lbs of propane, I should have a CCC of 1673 lbs before I add any water which is 178 lbs more than the 1495 lbs posted.

Another question is that the book with the motorhome states that the CCC equals the GVWR - UVW (including fuel and water in all tanks). Does that mean that the posted 1495 CCC of my rig assumes a full tank of gas and full water, grey, and black tanks? If so I can easily increase this by traveling with empty water, grey, and black tanks.

How can I confirm all of this?

Thanks.

As I said. Something is off in the calculation. There's no way CC is water in ALL tanks. That's 50 gallons fresh (with water heater) 39 black 39 gray (128 gallons) that's 1000 lbs in fluids.

Federal gov mandates weight stickers (yellow door ones) are supposed to be GVWR minus (UVW + full fuel + full LP). Obviously we're overestimating some weight.

The old CCC was estimated differently by each mfg which was confusing for the consumer. Yellow weight stickers were supposed to be more consistent.

To confirm all this? Load up and head to the scales. We estimate conservatively. I'm still trying to figure out the other 100 lbs we're off. But I doubt that would make of break a trip.

What we do know for sure is the what the dry weight is. We pull a unit up onto the scales, normally has no more than 1/4 tank, it gets weighed and prints out that yellow sticker. That's the accurate number...the rest is all what you put into it.
