Love my little 3kW ,6HP, propane portable generator with manual transfer switch...runs lighting, TV & satellite receiver, kitchen 'fridge and garage 'fridge, coffee pot in kitchen, master bathroom lighting and exhaust fan...
Just enough to make life livable for the frequent 2 to 4 hour outages we have in this rural, national forest area with dense trees. Ran 4 days in aftermath of the April 27, 2011 tornadoes across the SE.
My favorite thing about the LPG is the little squirt can sit there untouched for 6 months and it'll start on the 2nd pull of the recoil starter (it's only 6HP, a little cast-iron Chinese engine).... but it's 10 years old and the oil is as clear as corn oil.
If it hadn't been for a $7k expense last October for a new central heat/AC system (went 16 SEER, 98% eff. with dual fuel), I would have gotten a 12kW propane whole house genny, undecided on Kohler, Cummins or Generac. When I get closer I'll dig into it more.
