need opinions on tire pressures
We have a little 19 foot 2014 Bullet Premier I just put on a complete new set of the Goodyear Endurance 205/75R X 14 tires. They have a "D" load rating, putting their single max load single at just ov...

Oh geez. I have acually been trying to debate with someone that has single axle TT and a single axle point of view.
Everything you have said is worthless to the majority of us that have dual axle TTs.
On a dual axle, if something happens to one tire, like a blowout, or loss of the wheel due to a spun bearing. the other tire on that side supports all of the weight. If one is running their tires close to capacity, that means that tire will be damaged and will fail in short order. So those of us that are experienced, know to replace both tires on that side. Now if you are running signifignant reserve capacity in your tires, you may just get away with it. I will retire such a tire to spare duty, but not worry too much about it.
With a single axle ( a minority now days) you do not have this concern... Of course if you lose a wheel due to a spun bearing, you will have other more pressing concerns.
On another note: I find it hilarious that people with TTs will brag about their tires success over such short mileage figures like 6500 miles, as if that is a major accomplishment. It seems that people have VERY low expectations out of their TT tires.
The same performance on their daily drivers would have them screaming.

If LRC tires are sufficient to support the axle capacity, and someone puts on LRD, needing to inflate them to max to support your "dramatically varying weight" only means you're overloading the axle.
It is even worse than that.
TTs are sort of unique in that not only can the total weight vary by a lot in the course of a trip, but the way it is distributed can change dramactically.
My TT came with 5200# axles and springs. I swapped in 7000# axles and springs. My TT has two 42 gallon grey tanks and two 42 gallon Black tanks. Since we always boondock, often in remote locations, the TT comes home with full waste tanks quite often.
That fact alone makes for a dramatic change in the weight. Add in all of the other things, like my 5.0 cubic foot freezer full of necessitys on the rear rack. and all of the little stuff... It all adds up. But my additional 3600# of axle capacity and Michelin XPS RIB LRE tires can handle it just fine.:B
My TT came with a 3500 lb axle, which I replaced with a 5200 lb one. I run LRE tires which could handle 5600+ lbs @ 80 psi. No need for more than 70 psi to support the axle rating, but I run them at well below that because I don't load to over 4000 lbs. There's still a significant margin above what they carry, even though the pressure is much less than the max. Since anecdotal data seems to carry unreasonable weight around here, 6500 miles so far without incident. Including towing on occasion at more than 65 MPH (oh, the horror!). And, they're what the xenophobes around here would call "China bombs."
