The 35 psi is the pressure of a Standard load P tire and for this the maximum load is calculated for up to 160km/99m/h or if lower maximum speed of tire. The 44 psi is the maximum allowed cold pressure ( 18degrC/65degrF) by the tire-maker.
For laws of nature the tire may even have higher pressure but the tire-makers dont stand in for that, but means that warm pressure rising by temp rising in tire is taken into account.
The SL P tire can probably stand even 70 to 100 psi before it blows.
Also they dont support more loadcapacity at higher pressure, but unofficially higher pressure is also adviced to cover peak-loads , wich in my translation is to be expected overloading in some situations, like when towing.
The difference between that AT-pressure/maxloadpressure/reference pressure of yours 35 psi , and the maximum allowed cold pressure of yours 44 psi, is used for higher speed to highen up the 35 psi with a system depending on speedcode. Also used for alighnment often done at rear , a camber angle above 2degrees + or - ( wheels like this /-\ on the imaginary axle).
Your car has probably pretty oversised tires so could do with lower pressure in normal use.
And you are not allowed to go over the GAWR's , but it happens often enaugh, and then in combination with a R/L unequall loadivision, it would need higher pressure then given in Pressure/loadcapacity lists of tire makers if you would look the half gawr back.
If you give more information about car and tires , and also of the Camper and its tires, I am able to calculate a save pressure with some reserve.
Will give general text I used in other topics to show what is needed( done so I dont have to write it again and again).
Tirepressure advice is all about load on tire and speed ( and sometimes about alighnment - camber angle).
So if you can give details of car and tires , I can calculate an advice pressure with some reserve for things like, pressure-loss in time, unequall loading R/L, incidental extra load, misreadings of pressure scales,and misyudging of weight, etc.
This is from tires next and can be read from sidewall:
Maximum load or loadindex.
Kind of tire to determine the AT-pressure/pressure needed for the maximum load up to maximum speed of tire, or if lower 160km/99m/h/reference-pressure, wich is not the maximum pressure of tire.
Maximum speed of tire, most given as letter ( Q=160km/99m/h,N=140km/86m/h fi)
If you have offroad or tires looking like that , with large profile blocs that cover a part of sidewall, also mention, they are allowed lesser deflection then a normal road tire, then the tire maker used to determine the maximum load (to my conclusion the case for the Bridgestone tires on Ford Explorer in the Ford/Firestone affaire).
If you cant find all of it give sises of tire and Loadkind, then I will google for it.
From car next and mostly can be found on same plate as the original pressure advices:
GAWR and GVWR ( Gross Axle/Vehicle Weight Rating)
But best would be to determine the real weights in your use on seperate tires or estimate it as acurate as possible, by weighing per wheel(pair) or axle.
Maximum speed , you dont go over for even a minute in your use, eventually different for different situations, for instance when towing or fully loaded.
This apart from trafic regulations, if you drive faster then allowed give that speed. Nature punnisches with tire-failure, police only with a penalty.
Give all that and I will calculate and give a picture of one of my filled in spreadsheets in my answer.
