Hopefully I can help clear some of your questions addressed in your video up. I am in no way criticizing you just making observations and offering my thoughts.
I as well am confused on what you are asking for. I watched your videos and saw nothing on the door falling off.
As for the no insulation in the door these smokers are NOT insulated. They are designed this way. My master Forge is the exact same way.
The 2 holes in the bottom of the door is too allow any grease/drippings that get in the door to exit.
The reason the vents do not close fully is to allow air to enter. You MUST have some air for the burner to work and for your wood too smoke.
Your racks with no stops is fairly common on lower end smokers. There is no problem using them you just have to be careful. My Master Forge has stops.
As to the refinishing it is a fairly common practise for a manufacture to touch up a product before boxing. The paint may or may not be a perfect match.
The 1 hole in the lip of the water pan is so you can lock it in place on the rails. If you look at the rails where the water pan goes you will see a peg. this is where the hole in the water pan sits. My master forge is the same way. I didn't care for this so I swapped my rails around, now the peg is in the back.
From your videos it appears you are reviewing 2 different smokers. 1 is an ECB (elchepo Brinkmann) since the charcoal pan looks exactly like 1 in your video. The other is the Smoke Hollow
The ECB is just that cheap, the dents and scratches in the pan in no way effect its performance and will work perfectly fine. I think you would be hard pressed to find a charcoal pan for an ECB, that is in perfect condition, as they are just stamped steel.
I agree with you that the dent in the corner of the smoker should not have been there, it was boxed this way. That is the manufacturer not GM. I have dealt with GM quite a bit and have never had a problem with them, or there customer service. I have never bought a smoker from them either. I would be willing to bet they will compensate you for the dent. It will not affect the smokers performance it is only cosmetic.
