I think you'll only need 2 furniture dollies, one on each end. Everytime I try to use a 3rd in the middle, one of the three never has enough pressure on it and slides out anyways.
I picked up my 215 with 3/4" thick glass (dry weight 500+ lbs) and all I did was show up with one buddy. We put it on the two dollies and strapped it down. Then pushed it into the Uhaul using the ramp, then did the same to push it into my garage. I pushed it into the house by myself another day and then we had a tank lifting party.
I think that's probably the best idea is since its mid-week, to just do something similar and then find a good day for a tank lifting party when you have the stand setup and in place. Perhaps even have a meeting at the house and then everyone lift the tank for you.
Anyways, not to make it harder on you but now I'm getting a range delivered on Wednesday. I'll update on the timeframe but I won't know until the night before they said. Hopefully we can work around the delivery time.
