I have a 23" and a 19" tall. I will roll them under the cover of my outdoor kitchen when it rains. They are heavy, but very manageable to move.
I will say it here first, I have never heard anyone come on the forum to complain of a component failure. This includes wheels, fire boxes, gaskets and any other aspect that you can think of. Dennis just creates wonderful cooking instruments that are rock solid.
Not sure where you are in Texas, but I am in The Woodlands North of Houston and you are welcome to come by and take a look.
