Refrigerator Question

Just took our 2nd camping trip with our Trailmanor (the first one was just overnight)...everything went well and worked well....no problems!! When we got home last night, we put the refrigerator on AC and plugged into the house and I noticed this morning that things were not as cold as when we were camping! While we were hooked up at the campsite, the refrigerator worked great....as a matter of fact, we set up in the driveway the day before we left and plugged in the refrigerator and ice cube tray and the next day we had ice cubes and it worked great...the only thing I can think of is that we didn't level last night when we got home...also noticed some water on the floor under the sink this morning...I am assuming it came from the refrigerator because the ice cubes were beginning to melt this morning....any suggestions? We haven't tried the refrigerator using gas yet...maybe we should?? Thanks for your help! Also, there was another Trailmanor in the park where we camped! I understand that's quite unusual!
