On the place where the power cord for our A-Liner comes to the outside of the trailer, there is a sticker that says "This connection is for 110/125 volt AC 60HZ 30 ampere supply". There is a 3-prong adapter that we use to connect to our house current and underneath (the 3-prong pulls off) that is (we think) a 50 amp adapter. One of the campsites we want to stay at has only 50 amp service. Can we use it?
The adapter that you pull off is what allows you to plug into your house's 15
amp plug. When you pull that adapter off, you are looking at your trailer's 30
amp connection. It looks like this, right? Adapter
To use a 50 amp connection, you will need a different adapter. A 50 amp receptacle has four prongs. You can buy that adapter at any RV supply store. Here's what they look like: Adapter
When you buy it, make sure you get the one with the four prongs on the male
end, like in the picture. They also sell a 30-amp male to 50-amp female for use by 50-amp rigs that need to plug in to 30 amp power.
