How do I go about getting an old tank certified? How long does the certification last? Does it cost anything? what has been your experience with old tanks? I am looking to convert my truck to propane and am currently hunting a tank.

 

I think it lasts 10 or 12 years. I dont remember exactly, but it cost me $10-20.
Went to a large Propane distributor. Ask at an RV repair shop, they will know.
