How much air depends on you rigs weight, your tire brand recommendation from manufacturer. You check the inside tire of dual wheels with a pressure gauge just like the outside ones. Although is sounds like your rig may not have valve extenders that let you do this from the out side. You may have to crawl under and check them. If that is the case you should have extenders put on so you can check them often and easier.
You may also be interested in a tire pressure monitoring system- many types and brands to choose from. Tire minder, TST 507, and many others. You need to check the date codes on your tires to see how old they are since you down there looking anyway.

Tire pressures are NEVER checked warm. ALL tire pressure specs are for "cold" that is UNDRIVEN tires that are not heated by the sun either.

How much? Search these forums for something like "tire pressure" and you'll get thousands of threads on this topic.

BTW - Welcome to Irv2!

Dually valve kits for Motor-homes, Busses and 6-wheeled chassis

These really make the tire pressure checking a snap. I put them on when I bought new tires. There are other less expensive solutions as well.

Always check tires cold to determine if they are the correct pressure, however, I check them warm on occassion just to see if I have any substantial difference one from the other. That difference indicates you are losing air.

You shouldn't need extensions, you do need a dual foot gauge, available at any NAPA or truck stop.
Do not check tires when hot.
To get the correct pressure you need to weigh the rig and go to the pressure/weight charts for your tires. The pressure given is the minimum to support that weight.

On most gas Mh's it is not possible to check the tire pressure with the wheel covers on. Extenders are a good way to make it an easy task. The tire pressure is on a label next to the drivers seat. There is a big misunderstanding about this label. You will note that it has your VIN number on the label. This label is for your MH and only your MH. You will also note that this is a fleetwood label and is the tire pressure is for the MH fully loaded.

Huddjams,welcome to the forum. We need to know what kind of motor home you have. This would help answer your question.

Per the information entered at registration, it's a 35' Fleetwood Southwind. Of course that info is irrelelvant depending on tire size, mfg. and 4 corner weights

I have a 99' Fleetwood Southwind 35 ft. GVWR 20,500 lbs. and yes I did see the tire pressure cold on the side of the tires said 100 psi. I thought that their would be an warm pressure as well. I did think there should be a second valve for the inside tire. Thank you all for the helpful comment. I'm a new RV owner and I'm sure I will have tons of more questions. 😄

Get valve extensions put on. I just changed mine with new tires. The woven mesh I had were leaking and tire dealers said they are usually a problem. I had to go to a truck dealer to find the extenders.

Do not go by what is on the side of the tire. That is the safe working psi for that tire. Start with what 'your' motor home manafacture recommends and also check your weight when you are loaded for a trip.
As an example the psi on the side of my tires show that 120 psi is the safe working psi when cold. However the data for my motor home shows that my pressure should be 100 for my rear duals and 115psi for my front tires.
Check what 'your' specs should be!!!!

Huddjams, there should be a decal on the wall beside the drives seat or by the main door or on the inside of a closet door that lists the factory recommended COLD pressure for your tires. This is a good safe start pressure until you get the front and rear axles weighed. I bet you that it is going to be around 90 psi in the back tires and 95 psi in the front tires on that MH
