exchanging propane cylinder that came with TT

[danimal53]

I recently tried to have my 20lb propane tank refilled and it wouldn't fill. The person filling it determined it must be a bad valve. She proceeded to fill a second tank I had without issue. So my question, is there any reason NOT to just exchange the cylinder for a full one (at Menards, Walmart, etc)? I understand it's more costly, and you get less propane than if I did a refill. But is there any reason to keep the original that came with my TT? Or just exchange it and move on?

Exchange and move on. The one gotcha is that those exchange tanks are usually old, and some places won't refill them due to age. Most places will fill without a second glance, but a few won't.
