Yes, you are greatly overdoing things. Leave behind the extra generator, the impact tools and all but a few very basic hand tools. I got AAA premium coverage the RV tow insurance and used it once in 80,000 miles. And that was just to change a tire because I had the coverage.
Over my years and miles of travel, I have had to make a handful of repairs. Once I needed to caulk a leak. I had a door latch break and the repair required a screwdriver. I had to replace a water pump...another screwdriver job. On the road or at home, I have never had a job that required an impact wrench. I did need a breaker bar once.
