Taking both rusted propane tanks off my camper and chunking them but where/how?

Scrap metal dealer as long as they have a hole in them.

I'll let you decide on how to get the hole in there but if were me I would Pew Pew!

Take them to Walmart and trade them in for two full tanks.

This, depending on size. Or most propane companies

If an exchange place will take them I would give that a whirl.

Not sure what size they are, but many travel trailers have the larger tanks and they wont exchange.

I have small bottles

How small?

If 20 lbers just exchange. That is what I do when a tank i own needs to be recertified or has an old style valve. Those are the only times I use tank exchange. I want the full 20 lbs for less $s

I will that this weekend.....

With the 80% valves that are now required on the bottles, you are only going to get 80% of the capacity of the bottle.

Occasionally I get one filled but the majority of the time I just exchange them. I don't use that much propane to obsess over and the exchange is much more convenient. Last time I had one filled was at tractor supply and I think i waited the better part of an hour before I was helped.

I just take them to Cadenhead gas and it might be 10 minutes. I have waited longer then that to do an exchange.

Thats cool but it dont help me in San Antonio. My experience with having them filled is I have to drive further and wait. I can exchange them at any of the 3 gas stations within a mile or so of my house etc. Plus most places that fill them do not keep convenient hours, where as exchange locations gas stations, walmart, heb, etc. keep much longer hours.

Yep, for those that live in town an exchange might be more practical. Fortunately I have 2 places to refill as close as exchange places. It also helps being retired when dealing with their hours. When I worked I would have to fill on days off or get my neighbor to do it.
