I installed a hitch receiver on a 2020 RAV4 and needed a long handled 19mm wrench to get to the passenger side bolts. One of the bolts was really at a bottleneck. I was a little worried because 86 lb-ft of torque is a lot. The 19mm wrench is just over 16 inches long so I turned it really hard and it got the job done with no issues. Not even the wrench had a scratch. I didn't need the whole set but it was the only option. I was able to find a closed end and a long handle. I expect other sizes will be useful in other projects.
