For a starting point what size tires are these replacing, what is/was the max load of OE tires in lbs. at max psi., what is load in lbs. of new tires at max psi. if just a few hundred lbs. I would go by the sticker on tow vehicle for loaded/unloaded weight plus 5/10psi. for the larger tire. JMHO
Yeah the size designation he gave is a P tire which isn't a wise choice with a 11000 lb 5th wheel trailer.
However if the Toyo is a MT LT295/55-20 E tire at 35xx lbs capacity then the tire has plenty of capacity.
One problem we get into with installing large over size non OEM tires/wheels that will be carrying heavy loads is finding the best tire pressure for a good foot print and no carcass roll.
Check out this from Toyo website on page #26 for those size tires.
OP needs to weigh his trucks front and rear axles for using tire pressure charts. https://toyotires2-1524598101.netdna-ssl.com/assets/lib:toyo%20content/Application_of_Load_Inflation_Tables_20151020.pdf
