I need a de-humidifer

Hmm, I guess to each their own.

I use a 1200w heater, a 600w heater, a 90 pint GE dehumidifier, a Sam's ice maker, all while running my fridge on electric.

30 amps is 3600 watts although the government says we must derate this some percentage.

Now if it's time to run MW or toaster, I turn the 1200w heater off first

Chemical desiccant based units might work for storage but not in a lived in coach.

AMP draw a very BIG concern when on 30 amp! Will need to keep water heater on electric AND will also need a small electric heater in the wet bay not to forget the fridge as well as one or possibly two electric heaters. Oh, the electric convection/microwave.
Add it up.

Not going to rely on the E.M.S or switching devices on/off.

Not going to use the on board furnaces. As you should know the are VERY inefficient. Will use extend-a-stay and a ventless propane heater ONLY during daytime hours.

Thanks for all the suggestions! Good info!

Have always had a 30 pint dehumidifier in all our boats and RV's. Unless conditions warrant it, we take them off when using the boat/RV.

We use an electric water collecting unit often kept in the shower. Best investment ever. We can dry laundry over night. Condensation does not exist in our hybrid. Bought at Home Depot

We have a GE 30 pint that during periods of high humidity we dump twice a day! We very seldom have any moisture on the windows, and if we do it is just a small strip along the edge. We winter on the Oregon Coast.

Have you already tried the roof vent plus most distant window from vent plus electric heater by the window? (oil filled preferred).

OP's signature says they have 1000 watts solar, and I'm sure a generator on top of that.

I've used this Frigidairein a room at my work that had poor AC. Temp wasn't a big problem but humidity was. It held a 600 square foot room at 50% in TN in the summer.

My preference is the type WITHOUT a pump. Pump failure would be ugly. All you need is a slightly elevated spot where it can drain continually, either to plumbing or outdoors.

+10 on that. With a dehumidifier, the bigger, the better.

You really really want the biggest one you can find. We wintered i our fiver a few years ago. Two small ones did absolutely nothing and needed to be emptied at least twice a day. A big one will dehumidify a fairly large RV easily. Get one that has a drain hose and stick out a window or down a drain.
