A CM849/CM2100 truck would be much easier to start with if you want to play around. I assume the 2018 is your truck?

Thanks for that info! Yes, the 18 will be ours once it gets finished being built. Sounds like it would be wiser to buy a tuner for this one so parts can fall off, then get an older truck as a tuning test mule. 06-10 I assume would be easier to tune and still efilive compatible, correct?
