Chiming in a little late on this, but I do think it bears emphasizing that 27' is considerably larger than 23', especially in state park campgrounds. We are 4 months into a trip from our home base in the FL Keys and have been up as far as Cape Breton, PEI, and throughout New England. Many of the campgrounds we have stayed in had very few campsites that could accommodate 27'. One other consideration is that if you really intend on using both air conditioners, you will likely need 50 amp service which will further limit your options. As others have pointed out, it will be important to predefine what style of camping best suits you.
