A lot of good answers so far! I also agree with the A/C drip pan drain holes being plugged by debris! You have to get on the roof, pull off the cover, and take a air hose, or just do by hand, clean the bottom pan, making sure you have cleaned the hole's out! The A/C's on RV's just drain out on the roof, and run off!
About camping with kid's, no matter whose they are, I learned very quickly, kid's need something to do! If they are not shown what or how to do something, they get bored very quickly! Fishing, hiking, exploring, swimming, are just some of the things you can do with them to keep them entertained!
Here is a somewhat funny story that happened to me, when taking 5 kids to Myrtle Beach, to see the ocean for the first time.
I had just bought a "91" class A 36' Overland Coach, and we packed up all the BIL kids for the trip! The first thing I noticed, every time we passed a semi truck, I heard the air horn honk? So, the next time I got ready to pass a truck, I watched out the pass. mirror, there were these little arm's pumping up and down, out the back bed room window?!!
They had taken the screen out, and were going to town! I thought, not going to hurt anything, as I am a trucker, and had taught them this move!
So we get to the other BIL's house, in S. Carolina, and we all noticed a very bad smell coming from the bathroom area?
Up on looking closer, ohhhhh, the black tank was overflowing!
It was running down into the basement, and the smell was bad! Ask the kid's, how could the tank be that full?? And it came out, that one of the young boys, was fascinated by the way the toilet flushed, and ran all of the fresh water tank into the black tank and overflowed it? So, we scrambled to a RV dump station, dumped the tanks, filled the fresh water tank again, and had a quick coarse in toilet flushing! Then off to the car wash, to wash out the basement compartment that got soiled!
Long story short, we went on to the beach, got a campsite right on the beach, and had a great time! I was still trying to get the sand out of the basement compartment's 3 years later, from all the seashells that were hauled back to Illinois!
We went on many camping trips, after that, and when I ask, do any of you want to go, they always said yes!
They are all grown now, and all tell me they have the greatest memories of those trips!
Also, to note, I replaced the gasket under the toilet when I got home, as that is why it emptied into the basement instead of overflowing?
Rail!
