Global oil consumption helps to keep prices high and that benefits some countries that don't seem to like us a whole lot.
I hadn't considered cpap machines so I looked into how much power they need.
CPAP On Batteries Even if it meant adding an extra battery to avoid idling when the weather is good, the money would be recouped in about 3 days.
Someone here posted pics of their Sprinter setup and I noticed they had an Engel fridge. No need to idle your vehicle to keep your food cold with a fridge like that.
Don't forget the safety factor. Windows open, danger. Not to mention bugs and other critters that can get in.
There really is only two sure ways to insure safe, comfortable sleeping and maintain properly charged batteries and do it legally. An APU and/or shore power. In a van/sprinter that would mean a generator.
APU systems, with shore power, run about $11,000 installed. They are not nearly reliable as they should be. You can read old posts in here until you throw up and not read all the horror stories about problems with APU's. I am on my second. I always have them professionally serviced. The first did not ever pay for itself. It was in the shop for repairs too often. The second, brand new last year, has NEVER yet worked 100%. I have to take it back in, AGAIN, when I am home next time. Assuming I stay in the business long enough to wear this one out I doubt if it will pay for itself.
Yes, there is too much unneeded idling. It is just not as simple as some wish to make it out.
The ONLY reason we, as a nation, are not benefitting from oil prices/production etc is because we are not being allowed to develop the resources that we have, due almost 100% to the EPA. We have MORE than enough reserves to be free of ALL imported fuels, we are just not allowed to go after it. Plain and simple. One only has to look to the Dakota's to see what happens when development takes place.
