Ark,
No I didn't miss your point, I didn't say anything about not having an APU.
In fact the RV comment was an attempt at twisted humor of these all inclusive rigs all the while the owner is too good to stay at truck stops in fear of their rigs being scratched or dinged (I am being sort of sarcastic) - no reflection on anyone specific here. I met a bunch and a couple were, well too good to hang with the common folk (and Phil and Diane were not one who acted that way by the way, they were nice to talk to). My point is that the majority of expediters don't have a $200k rig, I bet a lot of these trucks are only worth $45k average and don't have APUs.
And the price of an APU is not a few grand, for many it is out of reach. I looked at a lot of them, there are a lot on the market and they are almost all the same, with exceptions of the controls and layout (A/C compressor compared to a glorified generator, etc...). What floors me is that most are glorified generators and Phil's (and others) solution is the best, get an Onan generator.
My comment "you got to do what you got to do" means just what it means. Many of US have gone to bed without idling the truck all night while waking up to a very cold sleeper (sometimes it is in the 20's). Many more have used a 'heater' of some sort that gave us that frost on the windshield in the morning, so it is a realistic view that many don't spend a lot of money to provide that bit of luxury in the form of an APU. You got to do what you got to do to make that money.
Now as for what OVM said, that is another thing I didn't think about but you know I find it intrusive what government does, and they enforce the laws sporadically, which my west coast trip proved that (sitting in LA with more trucks idling there than when I am sitting in Atlanta). But even though I feel there should be less government, I think that APU's should be a mandated piece of equipment installed directly by the manufacture for any truck that is built with a sleeper - no exceptions. I think that the sleeper manufactures (who don't run on tight budgets), can workout deals with these APU companies to put an APU on the truck when they install the sleeper.
Hope that clears things up.
