I wouldn't say it is dangerous but you are traveling with a pressurized propane system which incurs a certain degree of risk. I try not to if possible, the fridge will stay cold longer than I want to tow in a day unless conditions are extreme. Been doing it that way for 15 years and no ptomaine yet. Your choice.
Yeah that propane system is pressurized to 0.4 psi and has more safe guards then the vehicle fuel system.
No Flow Devices, Excess Flow Devices, Flame Proving, System Lock Out
Funny how folks will sleep with that same system operating but to travel with it on is tantamount to suicide
The appliances have these safeguards, the system does not. Excess flow devices will only work if a leak is large enough. If your fridge is running, the system still has to allow an instant increase in flow for your other appliances to light off and run.
Your trailer isn't working and flexing when it is parked, nor is the plumbing subject to damage from rocks or other debris, exposure to which will depend on the layout of your particular RV's system.
As for the quotes from Dometic and Norcold, they are saying their appliances will work if you are towing, they don't say it is OK to tow with them running because they don't know anything about the particular propane system in your RV. To do so would open them up to litigation.
As I said, I wouldn't call it dangerous but to deny there is any increased risk is just wishful thinking.
I don't care what people do but there is more than one way to look at this.
No flow device is on portable cylinders.....no hose connected/no flow
Excess flow devices are inside hoses....if a hose were to rupture/get a leak due to spit/rub a hole the excess flow will trip
System is only 0.4psi
Fuel system on vehicle 20K
Using propane is safer than running vehicle.
YES there are more than one way to look at things.
With knowledge and without knowledge.
Understanding how systems work and safe guards built in provides knowledge one can then use to make a choice.
I only post to try and provide information not argue about some one's choice.
I choose to use propane and keep my food cold.
Life is a risk. Try crossing the street....yet we do it.
Whether a high flow shutoff works depends on the volume of leak. When the gas valve for your furnace or hot water heater opens it doesn't trip anything. If they both lit off at the same time, there wouldn't enough flow to trip anything. A cracked or punctured line or lose fitting could easily result in a flow that is no greater than either.
Choose to do what you want, I've never suggested otherwise but don't tell people they have safeguards they may not have in certain circumstances.
I'll ignore the last statement, it isn't worth a response.
