Luckylynn, I have seen that done, with the AC. The people move a picnic table by the tent and placed the AC on that. They did the same mod's you did to the tent. Put a tarp over the tent and AC to keep the rain out.
I felt sorry for some of the tenter's. Ocean City MD. gets boiling in the summer and most of the sites are right in the sun.The campground does have a huge water park and another pool. Good thing.
I will have to post a picture of our tent with the AC in it. The AC is in the tent window ( somewhat like in a house window) We use a milk crate to set it on.The tarp is used as insulation on the outside of the tent with the rain fly of the tent to hold it in place. All power cords are inside the tent and just like at home we do not do anything to protect the AC from rain or sun. I hope this helps a little bit better to explain.
Here is the sight that we found out about how to do this.....
Tent camping with air conditioning?
Here is another one, this is not our tent,but this is how ours is done......
Air Conditoned Tent for those hot months We did not make our chute this long,we made it only 6 inches ,so ours sets much closer to the tent.
The tent we have now is the second one we altered for Ac so we had learned some things to do different.
If you have an old tent you should try it before you buy a new tent then you would know if it would be for you. My DH is great at doing stuff like this and our DD sews like a charm so between the two of them they made some great improvements from the 2 sights I showed you and just from things they learned from doing the first one.
So good Luck if anyone decides to give it a try......Happy Camping, luckylynn
