Unfortunately I did not find curb-weight of international on official website. But on some site I saw that's 7K lbs.So International GVW 22.9 minus curb-weight 7K = payload 15.9.
No. Not "7K".
No. Not "GVW".
No. Not "22.9"
If you want Crew Cab, and
If you want an 84" CA, and
If you want 4x4, and
If you want highest GVW
R, for the above configuration, where
R denotes the RATING, and where GVW without the R is the weight, then...
A strippy International CV Series Crew Cab 84" CA 4x4 cab chassis equipped with axles, suspension, and transmission identical to that of a Chevrolet Silverado 6500HD with the same cab and CA will have a
a minimum curb weight of 8,921 lbs (not 7,000 lbs)
a 22,
500 lb GVWR (not 22,900 lbs, and not GVW)
which would leave
a 13,579 lbs. payload capacity (not 15,900 lbs).
But, that is before any a options are added, and it also assumes the shortest AF distance. AF means "Axle to end of Frame", which you can choose. The above weights assume the standard 49". If you were to opt for a longer frame overhang aft of the rear axle, such as the 63" option, then the base curb weight would be 8,953 lbs, leaving a 13,547 lb payload capacity within which all factory options, the bed, the fuel, the hitch, the pin weight, the water, the Onan generator, the passengers, etc must fall within.
If you plan on obtaining a non commercial class A license, why are you considering the CV series?
Why not choose International's MV series instead? I'm not even sure that International will brand the 22,500 4x4 and 22,900 4x2 versions of the CV series. There was talk at one point early on of leaving the 6500 class of CV series chassis exclusive to the Silverado badging, because International customers really needing this kind of capacity would be better served by the MV series chassis anyway.
Not that it matters, if your wife can't live with the MV series cab then you can get the same CV series in the Chevy brand if it turns out that International's grille tops out at the CV 515, equivalent to the 5500HD Silverado. You'll have to see your International dealer for what was finally worked out, but I also heard that ordering may be nearing to a close for the 2019 model year due to the backlog of pent up demand. Something else to see your dealer about.
If you really need 4x4, why not look at the M2-106 by Freightliner. It offers far, far, far better visibility through the windshield, a more sloped nose for forward visibility, an all wheel drive option that comes from and is warranted by Freightliner as the oem, rather than the aftermarket second stage manufacturer set ups that Ford refers to after the fact.
Being a true medium duty, there are hundreds, if not thousands of more choices in equipment options... air suspension, air seats, air cab, air brakes. There are also a several different engine options... the Cummins 6.7, the Cummins L9 (oh baby, talk about power), as well as the Detroit Diesel DD5. Transmission choices are too numerous to discuss, along with rear axles... single speed, two speed, etc.
As far as "big rig" feel, the M2-106 can be had in lo pro configurations with 19.5" tires, and will have an ultimate lower step in height than the F-650 with 19.5s, never mind the 22.5's in the F-650 photo of your original post. This is in part due to the purpose built medium duty cab of the M2-106, which offers more interior height, and is purpose built for the chassis. The CV Series and F-650 essentially plop a pickup cab on top of a straight rail chassis.
Take a few days to look at all the medium duty trucks surrounding you on the byways and in the back of stores. How many F-650's do you see, compared to Freightliners? The M2-106 and 112 literally dominate the medium duty truck market, and have been doing so for years, ever since International fumbled on their Maxxforce engines. The renaming of the Durastar to the MV Series, with few if any changes to the cab, could be a way for International to step foward on a new foot and erase the checkered past.
You might be better served checking out Internationals MV Series, and Freightliner's M2-106 series, including their AWD model, if you really want to carry and haul the kinds of weights you are talking about, and want to have a better selection of chassis equipment to handle the job. Unlike those who would rather avoid the higher insurance costs and higher points burdens of a Class A license, you have a lot more options open to you over and above the two vehicles you initially identified.
