way better than any treager that's for sure, I have 2 and about the temp swings, its about playing with the heat deflectors, each smoker has its sweet spot. After playing around with them , its all bout set it and forget it.
Happened to me once at lake mead, saw a guy launching his 42 ft fountain by himself and offered a hand. all he asked was to back it down in a 3/4 ton Surburban. the weirdest sensation is when you have the brakes pressed hard near the floor and it keeps on going.
