Just some added info..
I purchased a Davy Crockett for home, Like it also, but it is larger, taller, and is heavy for one person to toss it in and out of an RV on a regular basis.
The PTG fits into the front belly storage easily and we then just carry a smaller bag of pellets or just toss them in a plastic container of some type for storage. We use a 'folding' aluminum table to set it on when using. The table folds up into the same size 'bag' as a collapsible camping chair.
It's a trade off of convenience and features.
The DC - Slightly bigger surface area for cooking, WIFI control on most(if wanted), better heat control, bigger, taller body, heavier and bulkier, choice of power - is 12 volt, comes with 120v ac adapter and additional hookups for 12v.
The PTG - Smaller, rectangular footprint, lid latches, I believe it is only 12 or 14 inches tall, lighter to carry. 120v only - need to use an inverter or small generator for boondocking. For weekending etc.. the PTG fits our needs nicely.
These units use very little power - just enough for the electronics and combustion fan mostly, and just a little more at start for a few minutes for run the 'hot rod' to ignite the pellets.
There is pros and cons to any unit out there.. Just get what you think will work for you and enjoy..
Hope this quick comparison helps..
