Generator is Onan 7000 watt diesel. It's 24 inches wide. So the plan is to install it long ways behind water tank. That will give over 2 feet of clearance for trailer to swing in over chassis. I'm not sure if that's enough. Generator is very economical (at 3500 watt eats 0.5 gallons) and since it wet cooled diesel should last 20000 hours. That's about 7 years of continuous use.
The rig is for boon-docking, my family refuses to conserve water. So sounds like we might have about 600 gallons for 4 people. Hope to last 2 weeks as per BLM 14 day stay rule.

Air brakes or hydraulics? If air, you can get factory many times, an air locker for the rear and front, or a mechanical Detroit no spin/locker as I have. Along with air ride suspension as noted, or seats. Although for an off roader, springs may be a better option.
A rwd with a 2 sp maybe better than 4wd.
You may want an 8 or 10 so manual or auto/ manual trans vs say a 6 so 3000 series Allison. Or a 10K motor vs the smaller 6-7 liter motors.
A GOOD sales rep, with most and larger, most are, they will get you with a sales rep from a bed manufacture, figure out what size you need, how it will effect the axle weights, then total weight. How much HP you need for YOUR interstate speed needs, overall low ratio based on tire diam. Torque, gear ratio in axle and transmission, if you need to pull an off road 40-50% grade, you can. OTR setups have a min 15% setup.
It's NOT just about weights! My truck is a city local setup. Highway, with a 175/335 non turbo diesel. Not good. 0-50 or 55mph. It does fine. I can pull a 30+% grade at 30k. Better than my dmax. Freeway, the 300/600 leaves the IHC behind!
ALOT to think about.

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.

Another to think about. Assuming you ARE PUTTING 15000 lbs on truck bed etc. How is
S that weight centered? ALL going on the rear? If so you will find you.have 21000+ on the RA. Max you can do.legally is 20,000. I'm going on the fact mine is just under 6000 empty.
So you may need to have a longer CA bed length, so some of that 15k goes onto.the FA. OR, design in a drop axle just in front of the RA, so on the hwy you are legal, but off road you raise it so it is not in issue driving here. Then get a 22-25K capacity RA to handle this load off road.
Or you may need a 15k FA with.some super singles to carry spread the load forward, removing it off the rear. By putting the.load more forward 've in the rear.
GCWR on larger trucks, may mean for city.driving, vs over the road. Can will it hold 55 on a 1-2% free way grade for local driving. Vs holding 60 mph for over the road interstate setup. This Is based on HP needed to over come how many tires are on the road, aerodynamics of the setup, actual weight, road bed type. Tire design and tread pattern.....
A LOT of things to think about.

I have not measured to the top of the chassis rail, but would guess something under 3' high from the ground - With the flatbed deck on mine, it is at 3.5'. I carry a 6000 lb triple slide truck camper on the back and about 600 lbs of batteries in the lower storage boxes while towing an 8000 lb 20' enclosed trailer that carries an additional 725 lbs of fresh water, 300 lbs of batteries, 150 lbs of gasoline and 100 lbs of propane in addition to our toys.

I'm confused about the numbers you posted. I'm interested in the GCWR and GVWR, especially the former. 3,200 pounds on the 5th wheel isn't much. This year's pickup trucks are rated to pull your trailer. I also don't think "payload" means what you think it means. Payload = GVWR - GVW.
Wrong, payload is GVWR - empty weight. GVW is actual weight of loaded vehicle.
