The hard point of giving advice on what to use is we each do something different. Based on what we do, we each have an opinion. We have a very wide spread of things to maintain. Cars, real trucks, powered machinery from small to large, implements, buildings, etc. We have found there is no one size fits everything design. That has given us larger sets of tools to make each job and person be the most efficient than most people have seen. It is a larger set of tools than my father and uncles could ever dream of. They also vary by location shops, support trucks, pickups, items on the machines, and emergency kits have differences. We run older paid for machines and we use them more than many people do. So we have the luxury of fine tuning the tools to the job. Very few items become toolbox queens.
In the tool mentioned our routine is the industrial brands. Wright, Williams, Proto. Mid tooth count but maintained and very smooth. For some of the tighter spaces we have high tooth count small head wrenches. The Snap on and Cornwell wrenches are used even though I have never seen a Cornwell truck around. For use on some of the implements we still have 70 year old 20 something teeth ratchets used. They seem to work better with a rusty fasteners. Again give years and maintenance some of the smoothest ratchets we have.
My favorite for years has been the old SK roto ratchet. Most adaptable to everything I do. Would I recommend it to everyone, no. To someone who works like me yes. For everyone I need to know how you work to recommend. Though the years I have seen many people struggling with tools that are well known but do not always fit what they do. There is the need to experiment and find out what works for you. If you have the volume of work it is what I recommend. In most jobs time is money. At times we need to experiment to see what makes the use of time most efficient.
) split to the lower end. Or go 308 and 338 to split to the higher end, but some big game regions still list the 375 as the minimum allowable and others restrict 'military' calibers so you may have to rechoose on the 308, and if you want/need to go to a bigger thumper level add something in the 458 class/group, and of course a little 22LR.
