Looks like you have hole for casters at bottom of the frame, I installed 4" casters on mine & makes life much easier when I need to move it around.
Good idea if you just can roll it around on a flat floor, not so good if you have to lift it off and on a truck, just adds weight and then requires a lot of tying down once its in the truck bed. This gen gets lots of time in the truck and boat.
