You have roughly a 55%/45% weight imbalance on the rear axle, which (according to the people at RVSafety.com) isn't all that rare on a motorhome. Not a great situation, but one many owners live ok with. I'd eyeball it from behind to see if a tilt is visible and take the actions others have suggested, but don't be surprised if not much changes. Just avoid making it worse with your gear loading.

If the axle with two ride height valves is the rear axle, I would raise the light side 1/8" over spec and lower the heavy side the same amount.
That will help some with weight distribution without getting either suspension or more importantly the driveline out of alignment enough to matter.

Did some calculating and made a list for your tire.
When I fill in my made motorhome tirepressurecalculator the axleweights it gives next.
Fr 11050 lbs+10% reserve / 113 psi
RR 20600 lbs+ 10% reserve/ 115 psi.
When part 3 used for axle-end weights.
Fr 114 psi
Then Left 5750 lbs uses 94% of loadcacity for the pressure, and right 5300 lbs uses 86% of the loadcapacity
Rear drive 125 psi
Then left 11700 lbs uses 95% of loadcapacity for 125 psi, and right 8900 lbs uses 72 %
So front at wich driver and co-driver are seated closer to, gives yust acceptable comfort
Rear right 72% could give some comfort and gripp issue.
Do you have for instance filled watertank at left behind, or other heavy stuff. If you can shift that other heavy stuff more to the right, it would give better balance,
Now my made list, is for searching back heavyest axle-end. For that it gives 95% of calculated axle-end loadcapacity, so you dont have to do calculations yourselfes. Front 1 tire, and rear 2 tires.
If you are able to shift weigt and weigh again, you can lookback the needed cold pressure in the list.
All thecalculations assume max used speed, wich you wont go over for even a minute, of 75mph, wich is max speed of tire here, I assume speedcode L.
List can be used for every tire with maxload 6940 lbs AT 130 psi Dual maxload 6395 lbs AT 130 psi
If you want list for axleweights to search back, I can make it too.

I have a 2019 Discovery 40M and knowing the coach, there’s nothing about the build that would make the left side 3000 lbs heavier than the right side. The two heavy items, refrigerator and washer/dryer, are on opposite sides. All the batteries are on the left side, the diesel scrubber, inverter and battery control compartment on the right side. The water tanks are slightly to the right side. In my view, there’s just nothing that would result in that much weight difference.
First thing you should have done is switch the rear scale pads side to side to see if the 2800 lbs went with the scale pad, or if it stayed on the left side. Those portable scale pads can get banged around a lot. I would go to a fixed scale and get a front/rear weight to see if it’s close to the portable scale weight.
The weight on my coach fully loaded with people, dogs, food, clothes, 100gal water, basement’s always loaded and full fuel was 11,620 on front and 22,580 on rear.
Also check the ride height on the rear to get them even. Raising the left side 1/4” will also take a little weight off the left front tire by reducing the sway bar tension on the left front tire.
