Window A/C for me too!!
For years, before I was able to Buy a Ram Diesel, my family and I went tent camping with a Honda van and a 5X8 utility trailer to carry all the "stuff". I have a 12X14' canvas wall tent and my aunt cut out a 15"X20" section which had two zippers and a velcro strip on the top. The space was for an 8,000 BTU window A/C. It worked great! Who said you have to be uncomfortable to go family caping? Soon I will be pulling a 22' "Hi-Lo" with roof A/C. I have already invented a wooden platform to support and anchor my 6,500 watt Honda generator, which I have in the bed of my Ram 2500 Diesel, to power all electrical appliances during over night stops. I say, do what ever make it comfortable for your family.
