I have been busy renovating a 1967
Globetrotter and went to address the old propane bottles that came with the trailer. Realized they were stamped 1952 - kinda old ha? These are steel (I believe) 20# tanks with new ODP valves. Here are my questions:
1. I have heard I can take these to any retailer that sells propane and exchange them for new tanks. Is this true?
2. If I can exchange them, will the store-bought 20# bottles fit properly on the tongue of the trailer? It appears someone had modified these tanks at the neck to allow them to fit better. You can see the "V" cut out at the top of the bottle in the photo. I don't want to spend money on two new tanks that may not fit my configuration.
3. Do I have to replace this set up with two 20# bottles or am I able to change the size of the tanks? If I purchase only one 20# propane bottle, will that throw off the "balance" on the tongue?
