Dehumidifier
As I have read the temperature changes in an RV cause condensation to build up. Would it be smart to run a dehumidifier inside it? I am thinking mostly while it is sitting between uses.

I run one when we camp during the early and late season. When we have to run the furnace. It's a smaller one, room size.

We run a couple of these when not camping: https://www.westmarine.com/buy/west-...18?recordNum=1 Of course, need 110v.
We've also used these if 110V is not available (just recharge in house): https://www.eva-dry.com/product/e-50...-dehumidifier/2022 Solitude 378MBS-R

We carry and use a rather large compressor type (GE - 22 pt. I think) dehumidifier. The goal is to keep the relative humidity in the rig between 40 and 60% - which it does well. Having dual pane windows, we don't have a problem with condensation on the windows, but high humidity can contribute to mold growth, problems with laminated wood products, and a number of other things. Other things to pay attention to are running the exhaust fan in the bathroom after showers long enough to evaporate the condensation on the bathroom mirror (too long and it will just pull in moist air from outside) and running one or both of the exhaust fans in the living area when cooking or boiling water. (Remember, the byproducts of an open propane flame are carbon dioxide and water - will add a lot of humidity to the inside air.) These requirements mean we end up using the dehumidifier whenever the ACs aren't running (they are great dehumidifiers) and we aren't in the Southwest (where relative humidity can be as low as 10% anyway!). We had it out and running a few days ago during cool, rainy weather in Iowa and Illinois. It pulled about a gallon of water out of the air per 24 hours and things were much more comfortable inside.
Factoid: adult humans exhale about 12 oz. of water in an eight-hour night while sleeping... per person. That's a fair bit of humidity in the bedroom at night.
Dealing with dehumidification is different if aren't in your rig full-time and have to store it. Depending on what region of the continent you're in and whether or not you have power in storage, you may have to take several approaches from desiccants to a dehumidifier with a drain tube leading outside.

So important you said it twice I think I am in between the two suggestions. What I have learned on this forum is there are a bunch of people with very large RVs. I think I need something in between the two suggestions. I have the 231rk. If in the camper, the AC deals with humidity on the hot days and heater on the cold. But I see people do use them so I am not asking a stupid question which I am always concerned about.

This is the one we got. Compact and works ok. Not as good as the bigger units but it removes water.
