As I read about the issues we have with our rigs, I am curious as to the tools you all carry with you. This is really a question for full timers or long term travelers since we have the storage and weight issues without the convenience of leaving lots of additional tools at home.
I have a tool bag with a normal assortment of screwdrivers, hammer, tape measure, pliers, wrenches, duct tape, gorilla glue. But when I wanted to clean my hot water heater, I could not loosen the bolt to drain the tank. The previous owner had mangled the head. I saw on youtube that a socket wrench (?) was needed. Do I buy just one to fit this bolt or a set? While my gennie was being repaired, I had the guys replace this bolt to make it easier for me. Any other tools that you found crucial?
