OK. I'm feeling pretty good about this. Assumptions in red ready for correction:
It's a 30k BTU A/C and Heat Pump "Reliable to Extreme Degrees" (LGRED) (heats down to -13 which I truly hope I never experience in the bus). The below is summarized from the service manual (located here
), and the installation manual (found here
; specifically portions relevant to the LMU300HHV).
Weight: 152.1 pounds
Dimensions: 37-13/32" x 32-27/32" x 13"
Below data is Listed as Min / Rated / Max
Capacity (BTU): 8,400 / 28,400 / 34,080
Draw (kW): 0.94 / 2.27 / 3.47
Capacity (BTU): 10248 / 28600 / 41600
Draw (kW): 1.29 / 2.32 / 3.55
For my case (flat against back wall of bus with infinite space on all side but behind and on one side of my choice) it looks like I need minimum 4" offset from the back of the unit to the rear of the bus. More is better for capacity, but worse for required platform strength.
I intend to build an large battery bank and solar array. I feel like I have to say this everytime I mention this; but I know it's going to be either complex or expensive. I will also have a backup generator to re-charge and back-up the battery bank.
