[VAL] can propane go bad?

[joepatwink@xxxxxxxxxxxx (Joe Winkler)]

Thanks for all the information about propane, even if some is contradictory. 
One thing everyone did agree on is that regulators go bad and should be 
replaced. Well, don't worry. I have already replaced the regulator, it 
leaked when I brought the trailer home, 18 years of setting in the sun was 
way too much for it.
  I am now thinking about just getting new tanks. I have to get the new 
valves anyway and the old tanks would need to be painted after I put in the 
new valves. I will call around tomorrow and check prices on valve replacement 
vs new tanks.
  One last note, I had turned on the furnace and left it on all night with 
the trailer pluged into the house current so I could check for CO with a 
120V meter. The meter said everything is OK and the furnace ran fine all 
night. I guess they would never be any trouble if we always camped in the 
driveway.
