Question, why is the stove on a slide out if you don't use it ? Everything is nice and compact. Where is your sink if you have one. I use a fish cleaning table with water source from 4.5 gal sprayer bottle with hand pump. works nicely ! Where did you get the grill top for the stove ? What keeps the folding wings for the top in place when closed for transport. ?
The stove is on slides because originally I thought the fold down front of the box would interfere with my ability to reach the stove top while cooking. I have used it both pushed in and pulled out. It kind of just depends on what I am cooking. If I were to do it again I probably wouldn’t use them. On the flip side they don’t hinder anything when not in use.
I use a foldable wash basin for dishes. I have my water tank wired to a water pump, hose and nozzle in the back of the truck so I do dishes back there. Depending on campsite I usually set up my table and chuckbox behind the truck so I can use the chuckbox and tailgate for food prep, cooking and dishes.
I found the griddle too at Costco for like $20. It’s awesome for family cooking, I use it for most meals. I keep a little one burner backpacking stove in the box also so I can boil water on the side for coffee or whatever. I’m sure you could find one on amazon to fit the dimensions you want.
In terms of packing it up the wings fold on top of one another and each piece stays put with small but powerful round magnets that are inlaid in the wood. The front has a latch. On both sides there are fold down heavy duty handles.
