Axle rating

Afrnd2all · 01-15-2018, 10:14 AM

I have a question about sticker on side of 5th wheel, that we are interested in. The GVWR of 5th wheel is 10000# The sticker ( see attached) says the axles are rated at 4400# Are these axles under rated or am I reading this wrong? Thanks for all the great info. This forum

12% (1200 lbs) on the hitch? (10000 - 1200) / 2 = 4400

4400 x 2 = 8800# on trailer axles. The other 2200# are pin weight on the hitch in the truck bed.

Let’s see if we can get the math correct?
Pin on a 5er should be between 15% and 25% so pin would be between 1,500 and 2,500#.
Then 10,000# - 1,500 = 8,500# and 10,000 - 2,500# = 7,500# on the axles.
At 15% pin you would be tight on axle rating, at 20% only 8,000# would be on the axles.

IF that RV is new, look at the tag on the axles themselves.. It's possible that it could be different.

Regardless of it being 15% or 20% on the pin, that's pretty at capacity IMHO... What's the model of that RV?

It is a 298 SRL Laredo. 2018

goducks · 01-15-2018, 04:18 PM

Shipping Weight 8910
Carrying Capacity 1090
Hitch 1410
Length 34' 6"
Height 12' 3"
Fresh Water 43
Waste Water 30
Gray Water 60
LPG 60
Tire Size ST225/75R15D

Way way under rated axles. UVW 8910. GVWR 10,000. That only leaves 1170 for gear.
And thats the dry brochure weight. Subtract the batteries and propane. 150 lbs.
So basically 1,000 lbs for CCC before you've put a beer or box of Kleenx in the 5er.

That CCC is insane for a 34’ 5er!!!
This is a subject that gets overlooked way too often, is very low CCC on many 5ers in the 32’+ range. Looked up a 38’ Heartland TH specs and it had a 1,400# CCC in a TH!!!
Our 32’ 5er has a dry weight of 9,820# plus water and propane of 434# (H2O weight of 374) and a GVWR of 12,360. The listed CCC is 2,106# which we are using about 1,600# of.

Another significant limiting factor for this model is the waste water capacity.

Shipping Weight 8910
Carrying Capacity 1090
Hitch 1410
Length 34' 6"
Height 12' 3"
Fresh Water 43
Waste Water 30
Gray Water 60
LPG 60
Tire Size ST225/75R15D

If you consider a carrying capacity of 1090, deduct 60 pounds for propane and install two 45 pound GP27 batteries (90 lbs) that leaves 1090 - 150 = 940 pounds. The spare tire isn't included in the unloaded weight, so add that in and you'd deduct another 50 pounds from the cargo 940 - 50 = 890 pounds of real cargo capacity.

Now, if you dry camp, you'd pull the trailer to the campground full of fresh water (43x8.3=357) with only 890-357= 533 pounds of available cargo capacity. The tough part is towing home from the desert or forest or lake after dry camping with full waste tanks. 30+60 (90x8.3=747) So, with 747 pounds of waste water onboard and a max of 890 (assuming your fresh water tank is completely empty on return) you've only got around 150 pounds of cargo that you can have onboard before you are at the trailer GVW.....

Many ultralight and superlight trailers are just not equipped to carry the load of "typical dry camping".... Our Cougar XLite has a cargo capacity of 2860 and similar sized holding tanks, we push very near to our GVW when returning from a dry camping trip with full tanks.

Add 8910 & 1090 = 10000, that’s the trailer’s GVWR.

Subtract 1410 from 10000 = 8590, divide by 2 = 4295 that’s the maximum load allowed per axle. The 1410 is carried by the tow vehicle.

They fudged it a bit to insure the axles - 4400# ea when added to 1410 exceeds GVWR.

Batteries and full propane tanks are part of the trailers shipping weight if installed at the factory. (Ref; FMVSS 571.110)

The 1,410 is the DRY pin weight, the 1,410 is 16.4% of the dry weight it will increase as the trailer is loaded. At 16.4% it would be 1,640# and would likely be closer to 1,800# to even 2,000#.

Everyone, Thanks for all of the input. Have not purchased this trailer. It is a serious contender. 100% sure we will not be dry camping. Wife and I are at retirement age. And are looking for something that will be comfortable for both us, For trips that would last a month or two.

Keep in mind that "camping for a month or two" is far different than dry camping somewhere for a long weekend.....I can promise. You will max out things to take. I had previously posted about my brother that came to see us here in FL and all he ever did was weekend/long weekend camping. Gracious, the things we have that they never considered (but wanted) once they got here was endless. Your weight is going to grow exponentially as you want/need more and more stuff to stay longer.

X2!
You will be suprised how fast that 1,090# CCC will be gone!
So far no mention of what the TV is, I would be looking at a 5er in that size with at least twice that CCC.

I had posted a similar question a while back on these axel ratings, I have the same 5er the OP is considering. I was shocked to see the axle capacity was only 4400# each.

Our Cougar had a GVWR of 10070#. The axles were rated at 4400# each. We weighed that trailer several times and never exceed 8800# on the axles. Usually scaled around 8000# to 8200#.
Our Laredo has a GVWR of 10000#. The axles are rated at 4400# each.
This trailer is, by my measurement, 2 1/2 ft longer than the Cougar, and the total tank capacity is 41 gallons less.
We selected this model because it had the floor plan we wanted and the GVWR we can handle.

Well its good to see Keystone went the other way on some...19K GVWR, 21K axle rating and 24K tire rating all on the same RV!

TV is a ‘17 F-250 6.7l turbo diesel Ecab SB

1 Don't take any beverages, mooch off your neighbors.
2 Use cg bath house for all those needs.
3 Take only dehydrated food and some slim- jims
4 Only pack one change of close, you can hand wash and rotate out
5 Only fill tv tank 1/2 way

It's a shame they don't make air bags for trailers, you could easily double that payload!

Obviously I'm being a smart a$$ but seems to me like Keystone is chasing a a magic 10k number so they can say "sure this can be pulled with these trucks". Buyer beware and congratulations on your awareness. Hope you find what you are looking for.

Flybouy, not sure you are too far off! These “Lite” 5ers with lengths of 30’ to 34’ and CC of about 1,000# would be difficult to do any extended trave in without exceeding the GVWR and axle & tire ratings! This might have more to do with “China Bombs” than the tire construction!
Much discussion on the forum and postings by “Weight Police” about the dangers of overloading the TV, what about overloading the RV???
Our Copper Canyon is 32’ and after accounting for propane and 45 gallons of water at 374# we still have 2,106# of CCC.
