I have a glass lined 40 gal indirect. Good luck lifting that. I used a dolly and put short pieces of 2 by 4 under it by tipping it, I was able to work it into place.
That's the way I move heavy things, including when I moved the P61a to a new spot from where it had been. The stove had been on concrete blocks that were on the concrete floor and I had to move it to where I had installed a slightly raised flooring system (camp basement) that had a raised hearth on it (end result, higher than it had been). I was fortunate that I didn't have to raise it by much, in this case and used scrap wood to build up the section between and build a slight ramp. Used pellet bags to give myself a slippery surface to slide the distance. I've used cardboard to move heavy objects too - in fact I need to quite procrastinating and move some stuff this weekend in which cardboard will be the method of choice. With the bags removed, you can see the ramp Oh yeah, I'm a smallish woman who is nearly 60.
Where there is a will, there is a way to get things done. Might not be done "normally" but it gets done.
Reporting back. I got that sucker in there over that pan with a bear hug. The key was I could not get a good grip on it and then I thought to put on some gloves with the nitrile rubber-like palm and that sure worked. It's right where it needs to be and I didn't destroy the pan, lol. Now to hook it up and hope it works.
I've always gone the bear hug and send it route. Works better when they are empty.... probably one of many reasons my back hurts most days too.
