Has anyone noticed how MH's seem to always have upwards of 5 A/C's on them? Whereas TT's and 5ers at most have 2 and cooling approx same amount of sq ft? Why do they have so many?
A rig with 5 is probably a entertainer coach with bunks for 6-10 people. A few MHs will have 4 if it does not have the bus air conditioning system. I have three and usually only need 1-2 unless it's just after stopping on a hot day. I'll run all three to cool the MH down because of the heat from the engine if going to use the bedroom and after an hour 2 will be enough. I consider my third unit a spare one as I rarely need all three.
