You did right with the pellet for what you want to do. I have a master built dual fuel and a master built electric 40. Both are vertical. The duel fuel is what I started with and it was a challenge to figure out how to make it work, first with the charcoal and then the LP. When I use that one I primarily do it on LP, but it’s tough to get it to keep from just starting the wood chunks or chips completely on fire.
The mes40 electric I got from my dad when he decided to go pellet with a traeger copycat. What I can tell you is that while the “heat” is a set and forget type of thing, you still have to add chips all the time. So it still requires quite a bit of monitoring. The pellet systems are the best for being able to not babysit it all the time.
You will also want to invest in a good thermometer setup that has remote monitoring if you don’t have one already. It may not necessary but it does help. A instant read thermometer is also a good idea.
