Some simple math regarding fuel economy

i think you can get mummies at walmart.........ht

 

Yes, Walmart carries Coleman mummy bags rated down to 10º or 20º F for warmth, the price is less than $80. Easy solution for cold weather sleeping without having to idle. Add some long underwear or other layering, a warm knit hat, etc. and it's very easy to stay comfortable in the cold.

My solution for not idling in hot weather is to lay on a towel to catch the "drippings" and enjoy a free "hot room". I can sleep pretty well in warm weather, just pretend it's one of those expensive spa "hot rooms" where they set the temperature at around 105-115º and have aromatherapy, etc. Even day sleeping in 100º weather with all the vents and windows open on a breezy day is doable. Other than that I resign myself to staying indoors during hot days. Night sleeping in hot weather is fine in most of the west, even in Phoenix the night temperatures dip to the 80's.... and whenever I have the option to spend the night at higher elevation remember that you lose about 3-4 degrees for every thousand feet of elevation gain.

 

For sleeping in a truck in hot weather, use a fan. It will help.

 

well i never have to sleep in the truck any more as i run tanker and im home every night. i run dayshift and most of my runs are under 2 hrs, but one way i found that helps is that i dont run the ac untill im on the highway. the ac compressor usally kicks the engine fan on which is annoying in so many ways, it changes the way you have to shift, its loud and obnoxious, and most engine fans take some horsepower to run.

now i do alot of big city driving with stop and gos so i leave the windows open and the ac off untill i get her rolling at the on ramps then its windows up and ac on and im just chilli'n...........happy trails

 

That's nice. I am glad you enjoy your heat.

Not all of us do. I enjoy my creature comforts and AC with low humidity when I sleep. To each their own.

That said, if I can't keep the truck at my comfort with just the windows open. (I bought a century with both the top and bottom windows) I won't hesitate to run the APU for AC in the summer and the espar in the winter for heat.

 

Also driving slower means less tire heat less tire wear, hitting a bump at 70 mph is not as bad as hitting it at 60. Bearings will last longer the engine isn't laboring so much. I drive 60 because I don't get to many days over 600 miles and I cant average over 61 mph on the log book but I notice a big difference going 60 and that's what I drive unless I go down hill.

 

i had a guy at work that looked at me like i was stupid when i told him that speed causes heat and heat destroys tires, he just looked at me and said well they cover the same ground how can you wear tires out sooner by going slower. some people wouldnt understand it if explain that 100 times............happy trails

 

If my camera on my phone were working I'd have taken a picture of the results of my jaunt from the Bay Area to LA with a very light load. 9.9 mpg with CA speed limits. Might have been over 10 but for the extended construction going on I-5 coming down into LA from the Grapevine in the early am.

 

That's pretty cool, most I've gotten so far on a light load was 8.8mpg pump to pump with idling two nights. I was surprised, course the load was 2,500lbs and only 2 feet tall lol

 

I'm running with a box, the load was one pallet.... 2000 lbs. Winds were negligible. Kinda fun pulling the Grapevine at 55+ ...

The truck is a 2012 Cascadia with 8 spd.
