Yeah sure...
I purchased the unit from minisplitwarehouse.com
http://www.minisplitwarehouse.com/AirCon_9,000_Btu_13_Seer_110v_Mini_Split_Heat_Pump_AC_A13CHEM4H4G09/p315964_9526459.aspx
It's a 9,000 BTU heat pump. It requires 110v 15amp. I could have wired it right to my convert because i do have a 30amp converter, but i choose not to do that. It uses a little over 2 pounds of freon, the indoor air exchanger is about 36 inches wide 12 inches tall. I had to remove one of my cabinets to put it in. :( But i'm glad it did. The unit has AC/Fan/Dehumidifier/Heater/Auto setting. The auto setting keeps the camper at 76 no matter what. I use it when i'm getting ready for a trip, it manages the fan speed temp and everything. It also has auto fan speed and tilt. fancy dancy stuff..
About the install.
I took the outside unit cover off, bolted it to angle iron on the heavy side, alum bracket on the light side. The angle iron runs in the well of the camper, it's bolted to the camper twice on the vertical side, and lag bolts on the horizontal side. The other angle bracket is aluminum a friend made for me that is bolted thru the camper.
You can install all the wires and copper tubes yourself, but i paid my friend $250 to install and check for leaks since he is a HVAC guy. There were no leaks. However, if i were to do it again, i would by a unit that needed the copper lines welded rather than nuted. Nuts works, welds are better.
As you can see, only one hole was cut. The water drain is the white tube coming out. IMO, it is twice as quiet as a roof unit, plus it is very very nice inside. The fan motor is very quiet and adjustable, my kids slept like rocks, and no hole in my roof, plus the DW thinks it looks pleasant.
In 97 degree Maryland weather, i set it to 73, and in the camper it's about 68. It will freeze you right out. Don't know about the heat yet, but i will keep you updated.
If you have any other questions let me know.
