Weight upgrades to FreightLiner chassis??

[boob-ears]

Have a coach with a 2010 XCR raised rail chassis. Would like to upgrade the rear axle from 17500 max to 19000 max.

Anyone tried to do this?? Would it entail more than heavier duty airbags? The tires are already good for 19220+ lbs; therefore I assume the 17500 limit is because of insufficient airbags.

Thanks

What is your CCC??? The coach I spec'ed was 4000 lbs. Do you have any idea of your UVW (empty) weight?

Did they install an new modified data plate showing the upgraded front axle? If it was indeed upgraded, they are required to install a additional data plate showing the upgrade.

They data plate is being mailed to me. The yellow sticker on the door shows en empty weight of 23270 lbs. I'm almost certain that is complete BS. It also shows a carry capacity of 3835 minus the weight of a full tank of water (716 lbs) for a net CCC of 3119. I think this figure is pure BS as well.

I strongly believe the empty weight is closer to 26270. I would LOVE to have the 4000 lbs of CCC as spec'ed by you. I'd be happy with HALF that figure.

I know it's easy to under estimate what you've loaded on board; but there's NO WAY I have over 3119 lbs of gear in this coach, even taking out the DW's and my own body weights.

People drop names all the time around here. And it is a well known fact that some coach builders mess up the weight numbers. If you dropped the name, you might find out the story.

Is this compatible?
Front GAWR 12,000 lb (5448 kg)
Rear GAWR 17,500 lb (7945 kg)
GVWR * 29,500 lb (13,393 kg)
GCWR * 33,000 lb (14,982 kg)

The figures above are exactly what I got after the front axle upgrade (done last Monday). It is a Forest River Berkshire 390RB (rear bathroom).
FR did pay for upgrading the front axle from 10500 to 12000.

Actual weights as weighed on a CAT scale (truck stop):

front is 11,400 (900 lbs over before upgrade; 600 lbs under after upgrade)

rear is 18400 (still 900 over)

This makes a total actual weight for my coach 29800.

I am well under the 33K for combined since toad is only 2600 lbs.

Thanks for the responses.

Wow. That sucks. I would call FL in Gafney directly. They are very helpful.

[boob-ears]

OOPS!!

Thanks all for responses. I am 900 lbs over weight on the rear axle, and have lightened the load as much as possible.

This is NOT limited by the tires.

I WAS 900 over on the front axle as well, but the coach builder upgraded it with larger tires (all around) and sturdier airbags.

My combined is OK, since my toad is very small.

My stated (by the manufacturer) empty weight as well as carrying capacity is approximately 3000 lbs "off", and NOT in my favor.

At this point, I'd rather not say the name of the manufacturer.

It would probably require a new heavier duty rear axle/differential. And for it to be highway approved, Freightliner would probably have to do the work and affix a new modified chassis info plate to it. The actual rear differental has a rating. Just what is the actual rear axle rated for as it sits? You need to know the axle rating before anything. And then the rear GAWR still rates at what ever the weakest link is.
