Hi; we're going on our first overnight camping trip tonight in our newly purchased (but used) motor home. The campground has 30 amp and 50 amp spaces. I'm trying to find out whether I can plug in my...

If you want to learn Ohm's law fine. volts/resistance = amps. You can use simple algebra to find any one variable if you know the other 2. Same with this, volts X amps = watts.
Bottom line, plug into either 50 or 30 amp service they both supply 120 volt service to all your standard house type outlets. Depends on your MH and it's appliances what you can use at the same time on 30 amp service. Take what others say with a grain of salt regarding what you can use at the same time. Our MH has a power management system. It's a 50 amp unit but if I only have 30 amp I can still run 2 A/C compressors and the fridge on A/C. Also have an electric water heater. The power management system will shut power to the second A/C compressor if I try to draw to much. Still too much the water heater get's shutdown, etc. Maybe your MH has that maybe not. If not, good thing is if you try to draw too many amps either your main breaker or the supply main breaker will trip. Then you'll know you went too far.
You do need to find out if your MH is 50 amp or 30 amp. No sense paying more for a 50 amp site if your MH is only 30 amp. If you do have a 5o amp rig you'll want to buy a 50 to 30 amp pigtail or plug. This will let you plug in your 50 amp MH when only 30 amp is available. Read the manuals that came with your MH and learn as much as you can. Then come back when you have more questions.
