Herm,
Congratulations on biting the bullet and ordering an Elite. You'll LOVE it
The Wonder Egg has the 9200 BTU Coleman Polar Cub A/C. I have two wall mounted thermostats located on the wall to the left of the galley. One for the furnace, and the other fot the A/C unit which also controls the heat strips on the A/C. They both work very well. If your A/C would have unit mounted controls, I'm sure there'd be a thermostatic control, but I'm not sure the fan would quit once the desired temp was reached, if you wanted to set it in that mode. (If anyond knows different, please chime in)
Have you considered adding additonal 12V outlets for convenience? I have 3 extra and have used them all at times.
Another option I find handy is the aluminum basket mounted in front electric jack. Ive'd used it for carrying a generator or strapping down some pre-cut, split firewood.
Welcome to the Oliver family.
