Those are the same tires I have on my my E-350 van. Check and see if they have a tread wear and temp rating on the side wall. Some of the old Firestones had a tread wear of B and temp of C. Worst ratings you can get. Remember the rollover Exploreres Ford had?

The tire guy is definately flakey. If 80 psi is "way high" then 75 psi is pretty high too ...many cheap gauges have that much error in them!! And if the max cold psi on the tire sidewall is 80 psi, then 80 psi is just right!

I use a mix of 78% Nitrogen, 21% Oxygen and 1% Argon. Works very well for me.

I used to use that size and load range on my pickup truck, although I used Michelins instead of BF Goodrich.
I don't know your weight, but seems your 31 ft Class C motorhome should have a higher load range than E. Sounds like you are running tires that are for light trucks, (pickups) I would opt for at least a load range F tire, if for no other reason than to be able to carry more weight with less air pressure.

The MAIN difference between air and nitrogen, as used to inflate tires, is nitrogen (if processed properly) is void of moisture. That pesky old water vapor is, well, pesky inside a tire.

Several race car series used to use nitrogen in their tires until they found removing the moisture from air provided virtually the same performance.

That tire expert has a lot to learn yet. I refer you to this pdf from the Rubber Manufacturers Association for accurate information. The bottom of page 25 lists 235/85R16 load range E tires. Keep in mind the listed air pressure for the load is the minimum acceptable air pressure, not the optimum air pressure for your specific situation.
If you do not know your actual individual wheel weights, you or anyone else is just guessing about correct inflation pressures.
