I've got a Ford F250 3/4 Ton 2014 SRW SuperDuty SuperCab XLT 4x2 6.75" Short Bed Gas Engine truck. The first question is about the tires which I think I know the answer to: I have Load Range E tires with a max load of 3195#. My GVWR is 10,000#. Focusing on the rear tires, my rear GAWR is 6200#, so is it correct to say that the weaker link is the axle (at 6200#) because the two rear tires can support 3195*2 = 6390#?The second question is that I went to get the truck weighed at a scale and the rear axle load (without camper) is 2820#. I believe this means I can put up to 6200-2820 = 3380# on the rear axle right?If so, does all of the weight of a truck camper go on the rear axle? If so, then that would mean that my camper wet weight can't go over 3380# right?I know the GAWR can't be increased, but do things like a rear stabilizer bar do anything for safety or is that just for ride comfort?

IMO never go over axle ratings. Tow with tires inflated to max pressure.The second question is that I went to get the truck weighed at a scale and the rear axle load (without camper) is 2820#. I believe this means I can put up to 6200-2820 = 3380# on the rear axle right?Yes that is correct. You can put 3380 on the rear axle. Make sure you account for other people gear and a full tank of gas. That # may/will be reduced.If so, does all of the weight of a truck camper go on the rear axle? If so, then that would mean that my camper wet weight can't go over 3380# right?Yes most of the weight will be on the rear. Some on the front so its hard to determine how much.What TC are you looking at? I know the GAWR can't be increased, but do things like a rear stabilizer bar do anything for safety or is that just for ride comfort?Correct. Any additions are just for stability and leveling functionality. You normally cant increase the GAWR.

While I do not advocate overloading your truck, the GAWR is usually restricted by wheels and/or tires. The axle assembly itself is probably rated for more weight than the wheels and tires that were installed on it from the factory, by a significant margin.

Yeah you are pretty much right. But don't forget that the camper itself is not all you need to allow for. There are passengers and all the stuff you put in your camper. Usual allowance is 1000lbs. It is quite true that ratings are usually conservative, how conservative you never know, but part of that is to allow for smacking the occasional speed bump or pothole or other roughness, it's there for a reason. It's best not to exceed your payload rating even if many people do. Still you will have plenty to choose from, just don't expect double slide outs and 11 or 12 feet of length.

Ok the Ford Sterling axle is rated at 9800 pounds, it is not your weakest link. Somewhere in your tires, rims, leafs, shocks is the lowest rated component.

I'll research which components are limiting me and replace those. Thanks!

Get ya a pair of air bags for the rear you will be impressed.

Beer is mostly water and a keg is ~16 gallons @ 8.33 per gallon, 133 pounds + the weight of the keg itself. I'd say at least 150 pounds.

Gonna need a dually ;-)

As you are intent on moving forward on this project. Be sure to look beyond the obvious. Have you compared what others are doing for shocks? With this weight on the back, your front shocks/coils (if you have them) will certainly be impacted. How about brakes? Going to a hotter use pads will provide more stopping power in extreme conditions such as mountain driving and panic stops. Is your radiator up for the task in extreme conditions?

Personally I would go the way DJ is suggesting, as well.

Ticki2 and Buzzcut are correct. The F250/F350 share the same 9600# rear axle. I went back in to the Ford Dealer's shop and talked to the truck techs before I bought mine.

Mine did not come with overloads either. But I didn't want to make the empty ride any rougher than it is so I did not add to the spring pack, I went to a local spring shop and had these 3000# overloads installed. It was about $450. But they do not come into play until the truck squats under load.

Lance 855S 2015

Loaded with water, propane and a moderate amount of your "stuff", figure that the 855s is going to be 3500# to 3800#, unless between 2012 (ours) and 2015 (yours) they built in an anti-gravity option. :R

Our Chevy now wears 3970# rated tires all around plus Timbrens and a BigWig anti-sway bar. Handles the load just fine.

When RV companies give a 'wet weight' do they allow for our gear in that or just propane and water?? I see the term used when I'm not sure it means what we think it means.

The wet weight as stated for the 855 does not include personal gear , food, 2 cases of beer or options .:)
