If you look at the first shot Lew presented, it's pretty haggard compared to now. This theme could be pulled off with better planning, execution, etc. My cab may not be the best inspiration, there are many things that could be better, the cab just hasn't been on my priority list because of time constraints. It's not done now, it may never be done.
I rushed into this project with no plan what so ever and it shows. Four years later, all I have learned is that if I could do it again I would have built something much more traditional, cleaner. It was actually my wifes idea to do the logs and she still loves it, she hand painted and carved the sideart from pinewood.
OP, I would recommend re-thinking this type of theme if it's something you want to finish in a reasonable amount of time. There are no plans to go by with this build, and you would really be winging it when it comes to logs. If you are completely sold on the idea, then I would say go for it.
