I'll can tell you from my Gravity Feed build...
It probably weighs near 750. It is 2" tube frame packed with insulation, 14 gauge inner and outer skins except for the door hinge side which is 12gauge. 2" rigid insulation....darn near 80 lbs worth. The firebox is 1/2" steel, transfer tube is heavy and runs full length...edge to edge. I am not a spring chicken as they say but I can easily lift and move a few things.
My intention was to be able to roll the smoker over the gravel roads around my house and barns. The rougher terrain is a problem so I keep it in the smooth concrete floor of the garage. The wheels are 8" foam filled and have some very high weight capacity. However, I cannot move the cabinet easily. It takes a rocking, rolling start and you'd better have the endurance to keep going because if you loose your steam after the first few inches...it's stuck. The tires get a slight flat spot and do it roll.
I find it too taxing to use the smoker so wind up using the RF much more eve though the thing works so extremely well. my 2 cents
