Confused about weight rating on my Fifthwheel

I have a 2008 Cardinal 30RKLE. I was looking at the data plate on the side of the camper. it shows my GVWR @ 12080lb but the GAWR (each axle) is 5200lb the camper. the sheet in my cabinet shows the camper UVW at 10220lb the math doesnt add up. the tag on my axle shows it as an ALKO T52 SLR is 5200. According to ALKO the safe load rating is maxed out with an empty camper what the heck is going on here? what am I missing?

Some of the weight( 2000lbs) is on the hitch. RV Manufacturers build right to the limit to put max amount of stuff in and keep the cost down.

How many axles do you have? 2 correct added them together for a weight rating of 10,400 LBS. Than you take between 15% to 20% of the camper weight (GVWR) (2,416.LBS) which is the pin weight that the truck will support. But to find your actual true weights, you should weight the camper and truck on a certified scale. Than weight each separately to find your true towing weights for your trailer and truck combination. Such as axles and pin weight of the trailer.


Most of us have down this and we also have weight the wheels on our trailers to find out the proper air pressure to run in your tires.

On a 5ver, approximately 20% (being conservative here) is on the hitch/pin. If you subtract 20% from 12,080 you have 9,664 lbs on the axles. Your 5,200 lb axles can support 10,409 lbs.

You have to remove pin weight from the equation. that weight is carried by your truck and not the trailer axles. So with a 20% pin weight of 2400 lbs,your weight on your axles would be about 9680 lbs....close but legal.

Most fifth wheels are the same our trailer GVW is 14500 ........... Our axles are 6000 each so 12,000 lbs there and the pin weight is approx. 2500 (It varies some) so max Gross weight is 14500.

All the math works just don't load any stuff in the camper, keep it empty and bone stock then all the weights will continue to work . Didn't they tell you that at the dealer ? rotfl

There is no excuse for the manufactures to build to max and expect to get cushion from the TV . no wonder so many tires blow out
