Neither unfortunately. I loosened both straps to the point of falling off, put my knee under the rear end of the tank and took that strap off. Then held the forward end with my arm and took that strap off. Once the tank was loose I set the rear on the ground so I could turn enough to reach the fittings on top. With the fittings off on top I set the tank in my lap, then wiggled out from under it and pulled the tank out from under the truck with me ( stock 97 1500 4X4), had to lift the side a little to make it clear.
I had the tank on the ground in 10 minutes. It then took me an hour to get the lock ring off, then over 2 hours to muscle the tank back in by reversing what I stated earlier.
This was all done in a gas station parking lot, with tools that I carry with me all the time. A jack would have been nice, but all I had was the factory jack, with no hardware to run it ( I had bought the truck.about a week before).

Speedometer update
Just a brief update. Yesterday I was tracing the source of a small leak under the drivers side dash area. Near where the parking brake and the hood release cable pass through the firewall is a bundle of wires leading up into the dash. I wiggled this bundle and basically unplugged and replugged all the connectors in that area. And voila, my speedometer started working. And as you all mentioned, it didn't make my truck run better. It did make me happy and I did the speed limit all over town.

Another update
Got in my truck today and speedometer isn't working at all.
I wiggled all the same wires plus a few extra, and it still isn't working.
The odometer and trip meter has always worked.
Perhaps whatever device, servo motor as suggested, is just old and crusty, and started randomly working?
Is it a servo that moves the speedometer pointer itself?
The voltages at the VSS all check out. and my OBDII scanner has a speed sensor monitor as well as a dashboard function that both show correct speeds when connected and moving.
is it very difficult to get into the instrument cluster?
Keep in mind, my dashboard is cracked bad enough that it has a custom cover on it that comes off easily.

Oh boy
I will have to wait and see if it starts working on it's own again.
Instrument clusters can't be inexpensive.
My $10 scan tool has a "dashboard" application that shows speed and RPM along with 4 other functions. And a dozen other sensor's data is available.
Maybe the warmer weather brought it alive and its getting ready to be really toasty until October in my part of the country.

96 Ram Info
My truck is automatic without a tach. The fuel gauge to the left of speedometer is either pegged on full until about 100 miles, then its pegged on empty! LOL
I assume that it's a float-electronic device that way out of spec. I'd love to even try to replace the servo, or at least have a look at it. I'm a solder veteran.!
