I believe the OP has posted additional info on another thread about this, so we know:

He will be over the truck GVWR
He will be over the rear GAWR
He will be over the rear tire weight rating
The truck is a SRW
The CG is behind the axle (we don’t know how far)
More than 100% of the campers weight will be carried by the rear axle.
None of the camper weight will be carried by the front axle
The rear of the truck squats when he loads the camper
The front of the truck goes up when he loads the camper
His headlights are alligned perfectly for owl huntin'
I doubt he has loaded any gear/food/water/passengers/etc yet
We still don’t know what camper he has
And he will be towing a boat on a 48” extension hitch

Hey, ya’ll can take it from here. I’m headed out to the garage to bend some 1.75” X .125” tube for a picnic table.

Actually, I think he is looking at duallys now, which is a very good idea.

Yes, he has picked out a '99 F350 dually crew cab 4wd diesel to haul his monster camper with. Hopefully he buys it. He'll likely need to do some spring work to the dually, but at least he will be starting with a much more capable truck than a short bed SRW.

I said i would report back when I got everything figured out with the company.

The camper I purchased is a 2012 Chalet Ascent S100F. Options incl generator, ac, 22" tv.

The placarded weight states 3328 with standard equipment, 418lbs water 60lbs propane, & 6 cuft refer. MSO titled weight is 3,300lbs

The actual weight (only the camper sitting on the scales) with options, 0 water, & 60lbs propane, 1 btry is 3904; big shock when I weighed it. It sure would be nice if the camper industry would accurately reflect the weight, as optioned, as it leaves the factory and get rid of all of the buyer guess work. I recommended to Chalet that they not market this model as SRW capable.

The CG was marked at 65" inches aft of the bulkhead and pictures of other S100F's were marked about 48-50". Brochure states 42". I did a personal test with 60lbs propane & battery & determined it to be 61". I put together an excel spreadsheet and calculated the CG to be 58" with 400lbs of water and some misc gear... just a few inches aft of my axle. Carl, Chalet Engineer, could not explain the errors of marking and would address my observations.

The Chalet Engineer, Carl, and their receptionist, Angie, were a pleasure to talk with. I found out that there are only 6 of these models built and only 4 sold including mine.

We are keeping our S100F and are happy with the feedback exchange with the factory. My goal, after I took a deep breath, was to inform Chalet that the brochure, placards/markings, and dealer info are in conflict.

We like the open floor plan, true 4 season camping possibility, fit/finish, outside storage, and the fact you don't have to crawl into the cabover to get clothes or other items (a waste of storage to some, a convenience for us).

Still weighing the option of 19.5's (bought used set of Vision wheels) and a 2000-2002 F350 7.3 dually (have a few on my list).

Thank you for the exchange of information.

You won't need 19.5's on a dually. The standard 16" wheels and tires that come on a '99-'04 F350 dually provide more than enough rear tire/wheel load capacity to haul the weight of your camper. The truck has 8250 lb rear axle weight rating and 11,100 lbs of rear tire load capacity, in it's stock configuration.

Of course, if you simply like the looks of the 19.5's, or just want truly commercial tires, you can certainly put them on the truck. Definitely not needed though.
