Since this thread was brought back to life and since I never responded after starting it I will now. I ended up selling the tank on Craigslist with the propane still in it. I think there was closer to only 75 gallons in it by the time it was picked up. A guy came with a trailer and we loaded it with the FEL on my tractor. The tank had two good hooks on the top which I assume are for loading/unloading purposes. I never heard from him again so I assume it worked for him.
It's always nice to know how these things work out. Thanks for the update.
