It is quite a bit smaller than my bigger grill. You just need to plan accordingly on what you make for tailgating or camping. I have a upper rack that helps. Earlier this summer I made 2 big pork loins and a port belly on the DC no problem. Looking at getting a rib rack so i can do at least 4 racks of ribs on the DC. We have a pretty big group come tailgate. So if we do burgers or wings I usually have to do at least 2 batches. Not a huge deal for me, just need to plan. Try and do taller meats. You can feed more people with a pork loin vs ribs. or chicken breasts vs wings.
I have a big griddle I have used on my DB, I don't have a smaller one that fits in the DC. in a pinch i have made eggs on tin foil for burgers.
If you want a big breakfast i would probably recommend a blackstone flat top.
We have a small group 3-10 people so I don't need huge breakfasts. Sounds like it would be a good option for me. Now to see if I can sell my roadtrip and masterbuilt smoker to offset some of this cost.
