Wvabeer,

Nice looking rig. I am guessing that you have 5000# on your rear axle. I have the same basic truck as you do. Unloaded with me and a full tank of gas, it weighs 6000#. Yours will also weigh 6000#.

You did the right thing with the air bags, rims, and tires. It will increase yuor GVWR from 7200 to 7700, just like mine.

My loaded camper actually weights 1700-1800 and ends up putting almost exactly 4000# on the rear axle.

I see that your loaded camper is around 2800#, about 1000# more than mine. Most of this weight will be on the rear. Have you weighed it? what's the rear axle number? I'd like to get a hard side as well. Thanks.

Thats right I am at 5000lbs on the rear tires. I don't have the slip with me but I looked thru my posts and the rear of the truck is 2700 and the camper is 2270. I won't be carrying much on the rear of the truck.

Then according to you previous post you are over the axle rating.
IIRC for 1/2 tons the limiting factor IS the axle (not tire/wheel) rating.
Keep in mind, we are all just trying to help you make good/safe decisions.
Many of us on the TC side of life are over on various ratings (GVWR, payload).
Axle/tire/wheels are considered sacred.
For good reason.

Safe travels, Bill

Correct! About the same as many 1/2 ton trucks...
Mini-vans, station wagons, SUV's, sedans...most will fall in the same range. ~ 1100#-1600#.
Something to think about.

My rear axle weight is at 4800 pounds loaded. That's with a travel lite 800sbx on my 2010 f150 crew cab 6.5. The truck handles it great. I have approx. 10,000km with the weight over the 9.75. I also tow a boat with this setup on occasion. When I rotate the tires I check for bearing wear. F150 has had the 9.75 rear end in the trucks for quite awhile. I see contractors overload these trucks and run them hard daily. I haven't been able to find any 9.75 failures online. I feel the ratings are a bit of a game. Bearing part numbers are the same for the 9.75 and 9.75hd. Hell my buddy minivan has a payload of 1100 pounds.

So far he has ignored us with that question or he doesn't understand how serious it is to over load Fords 9.75" semi float rear axle with just one small bearing at the end of the axle...... or any semi float rear axle.

Ford rates the '13 9.75" axle at 3850/4050/4800 lbs depending on springs/tires and wheel selections. I've yet to find the axle mfg rated capacity for the semi floater. Exceeding that number isn't a wise choice in the long run.

3850/2wd is the 8.8 the other two are the 9.75 all of which use the same bearing and seal. I feel it is as strong as the heavy duty version. I did my home work. I have had my rear wheel pass me going down the highway on my old 79 f150 4wd with 36 inch mud tires of which I overloaded regularly.

I totally agree. Lots of folks don't look at the semi/full floating aspect of a truck's carrying ability. IMHO I would not put a camper on a semi floating axle. I don't want the axle passing me on the hwy when it breaks. As important as rear axle weights and rear wheel weights are, axle make up is more important.

Not really...

9.75 the ratio 3.31
