How long does propane last?

Be sure to double check your tire pressures before hitting the road as the temperature drop you had over the past few nights could have lost you several psi or so and they may need to be topped off before hitting the highway.

Here in Tampa Bay it is currently 68 degrees with the day time forcast to warm up to 82 by this afternoon.

Have a safe trip!

Hi Neil v,

Don't want to hijack this LP related thread, but wanted to clarify the comment on tire PSI. It is my understanding that you adjust PSI readings down in cold, and up in high - temperature conditions? Tire manufacturers have charts to aid this.

If I'm wrong, great. If not, then danger of over inflating a tire in cold weather.

A safety concern, thus my reason for responding. Worth the Time to check to be sure.

Best to all,
Smitty

Removable Accu-Level Propane Tank Gauge with Magnetic back : Amazon.com : Kitchen & Dining
This and a cup of hot water will tell you the level of LP in the tank.

Sounds good but the reviews at the bottom are pretty negative, is there another gadget out there that measures propane tanks? wonder if these are available in RV shops?

That is a myth according to drivers.com

I have ducted heating system. I added and extra 4 inch duct to the underbelly to heat the water tanks area. I keep my heater set at 55 degrees while plugged in at my house. This is a very well built system and keeps my camper evenly heated. Before this system was installed it was hard to heat my 36 foot camper heated. I was using two portable electric heaters and one oil radiator heater going at one time pluss my gas heater set at 68 degrees. I went thru two seven gallon LPG tanks in one week. This system is so much better!!!

I appreciate the thread, but feel you will find many more hits on tires and PSI and temperature that reflect the standard rule of thumb of 1Psi variance per 10 degrees of temp change.

For me, and please anyone reading this do your own research, I set my tires at as close to the proper tire manufacturers temperature recommendations as possible. I do not add or lower, based upon different readings in extreme temperature swing conditions, nor at the end of long drive, where you will easily find 10 + PSI increase.

In cold temps say 50 degrees below manufacturers recommended tire setting temperature, I would expect to see. 5 PSI lower setting. So if 100 was what the tire should be set at, then 95PSI would be correct.

On real cold days, I let both the oil temp and tire temp slowly come up to proper levels, taking it very easy until they do.

Please do more research on your specific manufactures recommendations.

Be safe, have fun, best to all,
Smitty

Thank you Paw John,
I also have a ducted system already have a duct to the tank area installed by National. I have seen other posts they are happy with the system. Last week we were at 4500 ft was getting down to the upper 30's heater ran a lot in the evening set at 68, we turn it down to 55 at bed time. My furnace is easy to get at and run power to it under the cabinets.

That rule does not change the cold tire pressure according to Michelin, Goodyear and Drivers.com. Remember that a tire even in the summer is going to warm up around 50 to 75 degrees from the cold temperature its at before the sun hits it. On the highway you can expect a tire to reach a running temperature of 125 degrees or so which would be a 75 degree temperature rise on a 50 degree morning. Be wary of internet hits if they are not from the tire manufacturer, DOT or an credible source that has vetted things out as there is a lot of misinformation out there on any variety of topics.

Tire Rack did further testing on this and the results are that you do not adjust down when its cold out but follow the manufacturers cold pressure spec. The only exception is if you have the vehicle stored in a heated garage, then they reccomend adding an additional 1 psi for every 10 degrees colder it is outside compared to the inside of your garage of course without exceeding the max pressure rating stamped on the sidewall.
