For a SRW most trucks RAWR is indeed the OEM installed max tire rating x2.
The actual Axle weigh rating is usually more. This depends on the brand of truck and the year of the truck itself.
For most Ford SRW trucks in the 3/4T and 1T load range they use/used a "Sterling" axle. (I forget the exact years and ratings) Generally 1990's trucks used the 9.5" axle and newer Fords (about the switch point to the "Super Duty" series) use the 10" axle.
While the older model is rated lower then the newer one, last I recall looking it up the 10" version is rated for 9800lbs.
I carried a ~4000lbs camper on a 1997 F250 for many years. (total weight packed ready for camping was ~12000lbs)
I did however upgrade my tires+rims to 19.5" class "G" rated tires due to the limits of available tire ratings for the OEM rims.
Overloading your tires (causing excessive sidewall flex and overheating) is one of the primary causes of a blowout and something every driver wants to avoid (especially with a "top heavy" camper load in the bed).
