#10. - I assume you're removing the anode rod to drain the WH which is fine.
Why not loosely reinstall the rod after draining?
#23. - Do you really think its necessary to remove the propane cylinders? I'm thinking that you have to store them in a safe place when they're removed. Why not just close them and leave them in the RV?
#27. - Moth balls in the WH compartment? Are moth balls effective in outside cold temperatures? Just wondering?
#47. - Never thought about removing the RV plates when in storage - might be a good idea and probably won't hurt anything - just be sure to reinstall them when getting ready for the first trip coming out of storage
Agreed, it is a very good idea to loosely reinstall the anode. Not only does it make it easier to find when you get ready to de-winterize, but it prevents critters from making a winter home inside your WH tank.
Maybe because I'm getting old, but I don't see a reason to remove propane cylinders either. If yours are not covered, CAMCO sells a vinyl cover for them pretty cheap.
I've never used mothballs in any camper and have never had any pests (knock on wood). Their effectiveness is debateable at best.
I also don't see a need to remove the spare and license plate. There are inexpensive locking mechanisms available for the tire, and screws that only turn one way for the plate, if you are that worried about theft. For that matter, if theft is that big of an issue, I didn't notice a step to install a tongue lock on the trailer.
Additional items: the water heater should be turned off very early on. You do not want to be draining hot water, it's a burn hazard. In fact, whenever I winterize my TT, the only thing that is turned on is the water pump. All else has been turned off and allowed to cool (WH) or defrost.
Using cardboard to cover exterior accesses is a bad idea, rain will destroy it quickly, and it's thickness can cause hinges to loosen. If you don't already have bug screens installed on all your exterior access points, Tyvek (Lowe's or Home Depot) is a much better choice. There is no need to tape it in place (tape leaves residue), simply open the cover, place Tyvek over the hole, and close the cover, trapping the Tyvek between the cover and the edge of the recess.
All in all, a good effort, but I think you might have over-reached the definition of "winterizing". Perhaps "Long term storage preparations" would be a more accurate description.
