This stuff may help.
-Folding dinner tray (wooden) and you can buy a single for like $9 at Target or places like that.
-Crisper Basket and Tray +Cutting board + Q Matt - this particular crisper basket fits perfectly on the shelves of an MES40 so I can add and remove meat into/out of the smoker with zero effort or dropping things.
So this is how it all goes down for me.
Cutting and Trimming Meat
I put the Copper Chef Tray (not basket) on my kitchen counter.
The cutting board fits perfectly in the tray so I put the cutting board in the tray.
I lay meat on the cutting board and trim/cut away.
Seasoning Meat
I put the Q-mat in the Copper Chef crisper basket (is a little long but does fine).
I move the meat from the cutting board and put it on the mat and crisper basket.
I remove the cutting board from the metal tray and then put it in the sink or dish washer.
I put the basket on the tray (meat on qmat, qmat on basket, basket on metal tray).
I season the meat right there and any excess seasoning that falls through is CAUGHT by the metal tray :)
I have some pre-mixed seasoning or I just pull them all out and set them on the counter and season with whatever is in my kitchen pantry, either way it is easy.
Loading/Removing from Smoker
Once seasoned I carry the Tray + Basket + Meat to my smoker.
I set it down on the foldout dinner tray which is next to or near by my smoker (I use the dinner tray to hold the door open on my MES hehehehee)
I put all my meat probes into the meat (my probes are 6ft long on purpose for this reason).
With two oven mitts on my hands I add the BASKET (not the tray) onto my MES smoker rack(s). The mitts prevent burns if I touch the inside of the MES smoker.
I shut the smoker door.
I take the metal tray inside and rinse clean it if necessary.
Unloading time!
I take the metal tray back out and set it on the fold out dinner tray.
I open the MES door and use the dinner tray to keep it propped open.
Using oven mitts I grab the basket out of the MES and set on the metal tray.
I close the MES door.
I carry the metal tray + basket + meat back into my kitchen and set on the counter. The metal tray will catch any drippings and protect the floor and your clothes from becoming a mess :)
I use tongs (big or small) to move meat so it can be wrapped in foil (brisket for a rest,etc.) or put meat in foil pan for shredding (pulled pork and chucks), put the meat on serving dishes if eating immediately (chicken pieces, chops, etc.), do whatever I need to with ease since I am in my kitchen and working on a counter!
Conclusion
As you can see my process is easy, efficient, and far from being rigid. There is minimal moving of things around or carrying tools here/there, etc. Stuff stays in the kitchen with me while I work the meat (prep or serving) and the only thing that moves is the meat with it's whole tray + basket setup either when it is being loaded or removed.
I hope this gives you some ideas. Here is a shot of me working with smoked mini meatloaves. Meatloaf is a prime candidate for tearing up on you if you fool around with it too much or you don't have a good setup for dealing with it. So if this works on meatloaf, you know it works with everything else (I vouch for that).
