I was wondering about how expensive it is to generate electricity with my pickup truck to power my accessories in the evening compared to the 16 cents a killowatt hour electricity I have at home from National Grid (including the 1.8 cent a killowatt hour surcharge for wind-hydro power).
Figuring…
The inverter and wiring has a maximum output of 800 watts. In an hour, it can produce up to 0.8 a kilowatt hours of electricty.
The truck battery has a reserve capacity of 120 minutes at 50 amps draw at 12 volts.
Gas is $2.75 a gallon. A Ford Ranger uses approximently 1/2 oz of gasoline per minute idle, and it takes 256 minutes or 4 hours, sixteen minutes idling per gallon.
Idle the truck 20 minutes an hour to keep the battery charged. That means each hour it uses 10 oz of gasoline, or 1/12 a gallon of gasoline.
Adds up to…
About $1.50 a kWh for electricity. While it takes more then hour to produce that killowatt hour energy, that’s what the net cost is. It’s 10 times the cost of utility plant, but that’s to be expected.
A pickup truck’s engine and alternator is not designed as a dynamo to efficently generate electricity. The primary goal of the alternator is keep the battery charged up, and the battery is designed mostly to provide a high amperage output to the starter, to quickly spin a cold engine with significant resistance from congealed oil in the winter.
Alternators are at best 50-60% efficent at converting engine power to electricity, and that’s on top of an engine that is probably about 20% efficent at putting power to drive line. That means the entire system is about 10% efficent, far below the 30-40% that most utilities can create electricity at.
I normally am not a fan of rain when I am camping. I don’t like getting wet, and rain can put a damper in plans to go hiking. I worry about rain washing out the roads, or making the mud so deep and slippery the roads become impassable and I’m stuck on whatever truck trail I am currently on.
My truck cap leaks. By at least one of the windows, the fiber glass has shrunk around the window — probably from my use of Sterno to heat the cap — and allowed water to leak in whenever it rains. The wet isn’t bad, but it does make it damp.
The windows can’t be open when it rains — at least heavily — because of the slant to make the truck cap more aerodynamic. It gets humid under the cap, with no air flowing around to make up for the moist air I breathe out.
I worry about severe thunderstorms, as the I know laying in the steel truck bed, in a severe thunderstorm offers no protection from lightening, and the fiberglass would tear and shatter if a tree came down.
Yet, worst of all, it can be entrapping. There is relatively little room, especially with gear. I might have enough room to sleep in the truck cap, but it really isn’t big enough for doing any real living inside, with nowhere to stretch or move, without flipping down the tailgate.
Regardless, I kind of like the sound of rain on the truck cap. I can be loud, but it also is so soothing.
I have camped out plenty of times in the past in lean-tos and in tents in the wilderness. Yet, it’s not a regular thing, but more of an occasional thing. I much prefer camping out in my truck for the simple fact: I like having electricity.
As I’ve noted in the past, my truck has a 800-watt inverter hooked up to the battery, which provides electricity for my clock radio and lighting. I usually bring a string of LED Christmas lights for charm, but then also have a desk lamp with a 9-watt florescent light (equivalent to a 40 watt incandescent), along with two other 26-watt florescent lamps (each equivalent to a 100 watt lights).
It turns out that those lamps put out a lot of light. When I hear a bump in the night, or just need to run outside, I can turn on the lamps, and instantly have a lot of light. While a florescent lamp the size of 100-watt incandescent bulb might not seem that bright, as in a large well-lit room, in a darkly lit woods, they are very bright.
I usually use just a well focused 40-watt equivalent florescent bulb in my desk lamp for reading in the woods. I find it hard to read with a flicker of my white gas lantern, which also tends to be dimmer then the electric light, especially after white gas lamp starts to run lower on fuel, and needs to be pumped up again.
Indeed, one my favorite things to do when camping is reading. It one of few places I can enjoy the quiet without the distractions that are normally around. I find to read at night for hours, I need a good source of light to do it without eye strain I get with a lantern.
Electricity also powers my truck’s radio, along with a clock radio, chargers, and even a portable fan. It’s nice having music at night, and a fan to cool you. I like listening to the radio throughout the night, as it proves to be a good companion. You can get some of the strangest radio programs — right-wing christian talk shows — when your up in the woods.
Some people will say camping in the back of a pickup truck, with half a dozen things plugged is not real camping. Yet, it provides enjoyment, and a chance to get away from it all, and still provide the light and power I need or at least want to have a night.
This is a re-run from April 27, 2009, camping out at my parents house last year. This past weekend I put the cap on my truck, and look forward to the spring.

Last night was the first night of the year I spent sleeping out in the bed of my pickup truck. I have the cap on, the sleeping pads and bags back in, an it was a delightful 75 degrees out last night. The weather was amazing, the stars where great, and I built a big campfire in the back field a ways from my parents house.
I had forgotten the wonders of the night. Sitting out and listening to the spring peepers and creek flowing by. Watching the flames flicker in the campfire. Swatting the black flies. Wandering around the field, looking at the stars and the distant city lights. Tossing stones over the creek bank into the stream 10 feet below.
As the fire burned on, I took off my clothes in the warm springtime eve air. I hopped in the creek, illuminated by the campfire. It was so refreshing after a warm summer day, and it cleared my thoughts. I could hear the owl in the distance, and the water bubbling down and over the rocks. It was so wonderful. I got out of the creek, and up the bank, and quickly dried off with the warm air.
I sat and listened to some old Gunsmoke radio programs I had downloaded to my Mp3 player and on my truck’s radio. The hours ticked by and the moon rose. It was almost 1 AM when I climbed in the bed of my truck, turned out the florescent lead lamp, slammed shut the tailgate and went to bed. I looked up through the back window of the truck cap at the stars and closed my eyes to sounds of the crickets.
Morning came, and I awoke with the hot sun beating down on my truck cap. It certainly was bright and beautiful out. I heard the neighbor’s cows mooing to be milked, and the occasional neigh of sheep and squeal of geese and hogs. Morning had arrived once again. I folded up my sleeping bag and moved things from the cab of my truck back to the bed, fired up the truck, and off I went on this beautiful warm spring morning.
I do like my Ford Ranger. It’s big enough and powerful enough for me needs right now, but I would love to have a little bit more space for camping, and in a year or so I think it will reach it’s end of cost-effective life at 13 years of age. Maybe not, but I’ve been saving for three years and the reality is full-size trucks now have fuel economy in the range of compact trucks of a decade ago.

It’s probably no secret to anybody who reads my blog that I’ve been coveting a bigger pickup truck, with an extended cab, bigger bed, and a better off-road capacity. As I’ve also noted, I’ve been saving a big chunk of every paycheck to have enough money next year or the year after to buy that truck.
Yet, I realize it’s kind of silly. I still have a decent 1998 Ford Ranger regular cab short-bed, with only 95,000 miles on it. Driving only for pleasure, I probably will have less then 5,000 miles on it before the year’s end. It might be a bit old and rusty, but it still runs well with minimal problems. But I still want a bigger truck.
It’s not totally rational. I know I am buying into the consumerist mindset that I one level I supposedly reject as being vapid. But it would be so much more fun then my current Ford Ranger. Who wants to put money to upkeep a truck that I don’t really like that much, when I could be putting towards getting a new one?
It’s probably not a good attitude to have. I probably will drive more carelessly with my Ford Ranger and not maintain it as well as I should, secretly hoping that it will die, so I have to buy a new pickup. I need to avoid that attitude, as the truck is something I want to keep working,I also want to avoid financing as much as possible.
