Model 2910T is the heaviest of PCs because of it's length and 3 slide outs.
If I owned any of the longest of PCs, I would seriously consider immediately replacing the stock "E" rated tires with the extra-load "E" rated ones. They are available in two varieties by multiple tire manufactures. To get the full load rating, one variety requires only 83 psi, the other requires 90 psi. I would get the 83psi variety because the stock E450 steel wheels are rated to 80psi. I think an extra 3psi won't be concerning.
The higher-load tires increases the capability by 600 pounds per tire. That means the 4 rear axle tires together can handle 2400 more pounds than the stock ones from Ford. That provides enough extra margin to prevent tire-blow-outs.

An over-loaded rig is bad for many different reasons. But address the tires and you have taken care of your worst threat. I read on RV forums now and then, when a rear tire blows, the damage to the rig is most often very serious. The wheel well, the RV floor, interior cabinetry, plumbing, a propane line, electrical wiring, metal brackets for the mud flaps and other things, the damage can be done to all those things. Do yourself a big favor and do what you can to prevent a rear tire blow-out. And if your front tires are over-loaded, upgrade them too.
Put your original 6 "E" rated tires up on Craigslist and recoup some of the expense. At $30 per tire, that's $180 cash back. And no tire disposal fee either. The automotive charity I volunteer at would take good-thread used tires as a donation. They make great tires for donated work vans with bald tires. The charity gets much more for those vans when they don't need tires. Let the charity determine tire value and that will be the tax write-off.....if you are still itemizing.
